Some background: I wrote a game for Choice of Games a few years ago, but it did really poorly. I ended up playing and reviewing all the 100+ available COG titles at the time to figure out where I went wrong and ended up seeing a lot of different patterns in their titles and in what sells well.
At the same time, I kept seeing hints of a game by Emily Short coming out, who is one of the most respected IF authors with some of the most well-known games in her repertoire (Counterfeit Monkey, Galatea, etc.) But it was always delayed, and disappeared for years.
So I was excited to hear that it had been finished (with a little boost from Hannah Powell-Smith, another very popular author), I was excited to hear about it.
So for the game itself. My first go-to with a choicescript game is to look at its stats page. The best-selling games tend to have clearly defined and cleary differentiated stats, while the less popular ones often have confusing or overlapping stats. Here the stats are a bit overlapping: discretion vs self promotion, practicality vs daring, loyalty vs idealism, populism vs elitism. If you speak out to a billionaire and say you hate the wealthy (not an actual in game example), is that populism, idealism, or daring?
So in games where the stats are confusing, it can be hard to min/max, so I tend to just imagine a very specific persona and pick only what I think that person would do. This game responded to that very well, and I got a good story out of it, which is a good sign.
You play as a concierge to the rich. Billionaires ask the company you work for to arrange parties, trips, housekeeping, etc. Kind of like a fancy butler. I felt some connection with this theme as I work at a private school, and helped supervise a trip to Spain this summer, something I could not have afforded on my own. I don't work with billionaires, but sometimes with millionaires.
In the game, you encounter a series of challenging or intriguing clients. That's another aspect of this game compared to other CoG games: this is much more character focused than plot focused. I've heard some say it ends early; with a 500K wordcount, that's not really true. I did finish it in 3 hours or so, while I've had some CoG games take 10, but there are ones like Choice of Dragon that are finished in 30 minutes but don't feel like they end early. I think it's because the plot arc is fairly flat; there's not really a sense of continually rising drama with a dramatic climax; instead, there's a rolling succession of parallel character-focused subplots that each have their own rise and fall.
Going into more detail, rather than having dramatic overall events, we have things like examining in great detail the life of a trans billionaire who is uncomfortable with wealth; the life of a rich woman with a troublesome child; the life of fellow coworkers, bosses, etc. Much of the game is about reflecting on your views on them and life in general and on yourself and your feelings for them.
And reflecting is a key concept here in terms of other CoG games. The real big bestsellers tend to have actions have direct and dramatic consequences. Do you spare the life of the prisoner, or execute them? Do you take the evil crystal or smash it? On the other hand, a lot of the lower-selling games are reflective. Here's what you do: why do you do it? It's much more passive. This game is in between. You do get some pretty big choices, but a lot of things just happen to you and you reflect on how you feel about it.
This makes this game not really fit with the power fantasy that most Choice of Games fans look for. You're not stomping around destroying things. You're not constantly winning despite the odds. There are failures and takebacks (like a long sequence about a helicopter near the beginning) where you lose ground, something a lot of fans distinctly dislike.
But the games that do these things often win awards for writing, like Rent-a-Vice. Having the reflection, the failures, the character drama all are associated with games that have won awards. So if I had to predict anything about this game in the long run I'd wager that it will likely have middle-of-the-pack sales (definitely better than mine!) but be nominated for at least one writing award.
My particular narrative arc worked out well. I played a people pleaser who is mildly uncomfortable with the status quo but not enough to do anything about it. I ended up (Spoiler - click to show)becoming the CEO and marrying my coworker. I was interested enough to try another playthrough. I clicked through the first four chapters quickly trying to do bad. A lot of the early storyline was similar in the major plot points, although wildly different in the details (I somehow picked up an aunt I didn't have the first time). Later chapters were completely new material; in my first game I had several chapters about blackmail, while in my second I had a kind of international investigation storyline, which was very cool. Overall though I don't think it sells its branching very well; my first playthrough looked like I had hit up most major content, while the second was quite different. Signposting that more content exists is hard (more greyed out choices than we have here, chapter numbers with subletters, etc.).
I liked customization; I was able to refuse a drink and say it was because I was a latter-day saint, which I've never been able to do before.
Overall, this feels like a story about real people in real life situations. It feels like a biography more than a fantasy novel. I like to think of IF writers as opera composers and I've often thought of Emily Short as like Verdi, finding some similarities in their tones and settings. This is more like Beethoven though, with a clear aesthetic free of unnecessary clutter.
I don't think this will be a bestseller. But after having played more than 100 of these games, I think it's unique and high quality, and worth playing. I got really burnt out after playing them all and have started a few I never finished, but I played this all the way through in one setting, taking it to the library and reading it on my phone there, and even replayed it. I'm glad it was published; it would have been a terrible shame to leave this work incomplete and in storage.
This game was pretty fun; it honestly felt like an old AD&D campaign module. You have a magic user and a warrior with an enchanted blade, you have to buy equipment like rations, there's a miniquest in the middle with a mysterious city, then a couple of dungeons and a big scaly boss.
The idea is that you are on a quest to exterminate some rampaging lizard men. You have to travel through a long desert to do that. Also, along the way, you have to play both characters. This has a few slight drawbacks (mostly making it harder to save) but feels very dynamic, especially when infiltrating the city, and makes the game more enjoyable.
There is some randomized combat in places (so saving often is very useful).
In general the game seemed pretty fair; there were places where I had to reload a save to grab an item but each 'area' seemed mostly self-contained.
I did struggle with the parser from time to time; for me the hardest parts were the gate doors (Spoiler - click to show)I tried LOOK IN PORT, OPEN PORT, SEARCH PORT, PEEK IN PORT, etc. before the game suggested LOOK THROUGH PORT. Occasionally the game would say I hadn't done stuff that I actually had done; in those cases I reloaded the beginning of the area and ran through it again.
Overall, it was a big game, and one I can only recommend to someone with patience and the time to try and retry. But it was fun, and I would recommend it to such a person.
This game uses a parser that seems to be keyword based rather than grammar-based. It doesn't use a trained AI model, instead using the author's own custom engine that doesn't scrape internet data. I thought that was a lie since when I typed Overwatch it mentioned it was a Blizzard game, but I checked the github code and the author hand coded quite a few video games with their studio because it's the answer to a question in one of his games.
So this is a pretty unique thing. The author previously used this system in his game Thanatophobia.
This game has various background images and a 3d model of a girl wearing a dress. Later on, a young girl in a swimsuit pops up, although you can tell her to go away. The characters generally just perform random animations, usually not connected to the game.
The plot and puzzles are structured a lot like Blue Lacuna. Both games have a core element of key plot details, but they drag them out by making them timed in a sense; Blue Lacuna makes you wait until night, while this game will say 'I'll tell you more about that later', and you have to ask again later. Both games also include a lot of ambient nature stuff you can interact with while waiting for the core plot. Blue Lacuna has the island, while this game has random spots you can visit like monuments or national parks or even the sky. These usually don't contribute to the story, although sometimes they have interesting details. Both games last very long due to these mechanisms, while they could be far shorter without them (which could be a pro or con).
This game includes puzzles in two forms. First, there are random trivia questions. These aren't essential to the game, it's just something that pops up in the 'touristy' areas of the game.
Second, there are clues in the form of cryptograms. You click on a letter then type something to replace it with. It's actually a really nice system for cryptograms, lots more fun than doing it with paper because it allows for quick exploration. I usually deeply dislike cryptograms in games but this was fun.
Overall, I had fun for the first few hours typing 'in character', but for the last hour or so I just typed random junk to get through, like 'yes', 'i see', or even just every letter of the alphabet, although sometimes I commented more.
I didn't really enjoy the child-looking girls in skimpy outfits; especially when a romance option was available. The game even discusses the three forms of love (philos/eros/agape) but kind of picks one for you (I think? I refused at first but then relented later to see if it was story critical, which it seemed like it was).
The actual storyline is pretty good, about a young girl in the late 1800s who had the abilities of a medium, able to consult spirits. I actually really liked this main storyline.
There is a darker reveal later, and it contains some things I'm really uncomfortable with it, specifically (Spoiler - click to show)directly telling the player to kill themself. I know enough people that have (Spoiler - click to show)attempted suicide that I really don't want to see this kind of stuff in games; I think it can be handled in a sensitive way, but this isn't it (from my point of view).
Overall I was very impressed with this game, and thought about giving 4 stars. But I think the interactivity could use some tuning in regards to main plot vs side action. The types of characters I didn't care for but are normal for some types of VN games. And the content in the dark area was a little too dark for me. Technically, this game is very impressive, and I had fun with much of it.
This game is a hefty Inform 7 parser game set in a bunker city in the planet of Venus, with a horribly dystopian government where the greatest good is turning in others to the government.
The game involves numerous factions and parties (with different endings depending on which of two you support) and crossing and doublecrossing.
There's a lot of death, too. This PC's bodycount is one of the highest in games in recent years.
The game is very open in nature, with many actions being able to happen in any order. This leads to a lot of freedom, but makes the early part of the game fairly overwhelming. The hint system is also all available at once, due to the non-linear nature, and it can be difficult to find what you're looking for.
Overall, the game simply needs more polishing, but it is a good game at core, and is one worth having made.
One thing I struggled with quite a bit was the directions, which are INWARD, OUTWARD, LEFT, and RIGHT. It was hard to abbreviate these, as L means 'look' and IN and OUT map to inform's Inside and Outside directions. To be honest, I would have preferred the author just used the standard Inside and Outside directions and made Inward and Outward synonyms for them.
Giving 3 stars for now but would be happy to bump up if an update is made in the future.
This is a large, ponderous game with many attachments. The image I had when starting was of a gigantic hamburger, one that you'd get at an artisanal place that is far too large to fit in your mouth. You pick it up; it looks good. You eye it, go to bite, hesitate, turn it. A piece of lettuce drops out. You grab it, but an onion is slipping out the other side. So you just start eating, bits dropping here and there, no longer able or willing to manage it all, just enjoying the burger.
The concept of this game is that there was a (fictional) game released in 1996 that was like Photopia ahead of its time, less focus on puzzles and more on story. But it's intentionally made to be like other games of that period, so I guess less like Photopia and more like In The End, which is referenced several times.
Seven years later, someone releases a transcript of the game, which becomes well-known, so a new round of criticism is generated.
This game, in the fictional history, was buggy and received poor reviews. Then, in 2021, the author was approached by some critics/fans who want to do a critical version of it, which he agrees to while they update it (kind of like the Anchorhead update and the Cragne Manor tribute, I suppose).
This game consists of the 'revised version', with an accompanying booklet with the transcript and some art. The revised version has art as well. An in-game guide consisting of critical materials is available in-game, slowly increasing in scope as you proceed.
The art is one of the highlights; the style is unique and well-executed, and the game may be worth playing for the art alone.
The game concept is that you have the ability to remove entropy from some sources and imbue it into others, having been gifted that power by an orange-eyed demon woman in your youth.
It serves as a metaphor for involuntary inaction, similar to ADHD or depression, where you can only use some external impulse to compel yourself to complete some task.
Your mother is dying in the hospital, and you need to go see her. There are several obstacles in the way, though.
Besides the main goal of the ending, there are many mini-deaths along the way. The more you get before the end, the better ending you get!
Except...even if you only get a few, you can see what the ending would have been for the other options. I only got 6 points, but I wasn't super motivated to see the other 27.
And let's talk about why.
This game is very polished. It had numerous testers, and it feels like it. There were only a few times I felt like there were 'bugs', like trying to (Spoiler - click to show)OPEN DOOR while on the roof and having it say that that's not something you can open. Overall, though, I'd say it has a high level of polish for a game in general, especially one of its size.
Where I found some difficulty was in knowing what to do a lot of times. I felt like the game swung between no details and overfull details for clues sometimes. Like finding deaths; I really couldn't figure out the mechanics behind finding deaths at all. There were no exposed electrical lines or broken glass that could obviously hurt me. And things that were dangerous (like a heavy tree branch) didn't respond to what I thought were death-inducing things (like pushing them). The hint menu has dozens of hints, but none of them at all are for the deaths except for an explicit listing of the exact actions you need. In the main storyline, too, I often found that the things I got most stuck on weren't in the hints at all. I suppose I was just on a different brainwave.
It might have helped to highlight relevant features in some way. For instance, the (Spoiler - click to show)AC unit is mentioned early on in the first line of the paragraph, in the middle of a list of a bunch of non-useful material. Given its significance in the story, it might have merited more prominent place, nearer the end of the paragraph.
Fortunately, the game is implemented well enough that even while struggling there are generally good responses to obtain while looking for something to interact with.
The three layers of Drew Cook (the real one, the author one, the PC one) all blend in interesting ways, positive ones, I feel.
It's hard to evaluate the quality of the in-game writing. I think I would like it, had I found it in the wild; however, all of the in-universe reviews, mostly written by the (real-world) author, praise the quality of the writing. They'll say (paraphrase) 'the writing was excellent, but the bugs were terrible'; it came up more than 4 or 5 times. It's kind of like trying to judge the natural light of the moon when someone has set up a dozen spotlights aiming up at it in an attempt to brighten it. Does this artificial praise really affect my perception of the prose? It's hard to say, and it would have been interesting to see how I felt about the writing quality without simultaneously reading a great deal of manufactured praise for it. However, I do see the reasoning for it, for otherwise why would this game have been preserved?
Overall, I think of lot of people when looking for parser games to play are looking for something that's not super buggy, that responds to most inputs in a helpful manner, and that has a nice outer shell of story, setting and/or (in this case) art. So I think most people will be pleased with this. It made me think quite a bit, and I could see myself revisiting it.
This game is set in the Little Match Girl universe, which is very different than what it sounds like (to me it sounds like a drab and depressing slice of life series based on Victorian London, whereas in actuality its about a time-travelling assassin).
In this one, you have to take down the Snow Queen and her army of henchmen spread out over many worlds. In the meantime, you can add members to your party (up to 5), gain powerful abilities and engage in turn based combat (none of which were features of the previous Little Match girl games).
I had two experiences with this game, one 'okay' and one great.
In my first experience, I just plopped in and started exploring. I got confused by the large number of exits, especially diagonal ones, and I had forgotten the key feature of Little Match girl games (remember below for anyone in a similar position). Once I figured out how to go to other worlds, I met people but no one would join me. I kept gaining more abilities on my own and I was worried I'd get through most of the game without ever finding someone to help me.
So I asked for help from the author, and restarted. My second experience was much better. The three things that helped me were:
1. Keeping an actual map (I could have gotten a fairly early companion if I hadn't missed a room)
2. Remembering the key feature of Little Match Girl games (very light spoiler) (Spoiler - click to show)examining fire takes you to new places
3. Realizing the key to getting companions (moderate spoiler, got from author): (Spoiler - click to show)each companion requires one object from another world, and there's no companion in the first world.
With these in mind, I had a great time. There were some fun puzzles, and a variety of combat.
I'm actually interested in this a lot, because as an author I like to learn from these games, and they cover so many topics that at least something is always relevant to my current interests. The last little match girl game had an escape room that I liked, and I read it right when I was working on an escape room.
I play this game as I'm working on a combat mini-game. I had learned from someone else that having multiple antagonists made combat more interesting, and I was working on a system where you had a couple of robots with you you could program to fight.
So seeing how Ryan Veeder approached his combat was really interesting. Most randomized combat doesn't work well in IF, with Kerkerkruip being a major exception, but I think this one works well, especially with using HP to fuel attacks, even using HP to heal other's HP (but only one person being capable of it), as it can become a kind of resource management puzzle.
Overall, Vorple is working well here, with some surprises with sounds and colors. A couple of times when restarting or right after saving (maybe a coincidence?) the game automatically skipped through some cutscenes (like the very ending one), maybe because I had hit a lot of keys and there was a delay? Not sure, but I had to UNDO multiple times to see the ending correctly as it was just zooming past me. I'm almost sure it's something on my end but I'm putting it in the review in case it's useful for the author or happened to someone else.
I liked the plot threads about Ebenezabeth's overall growth and the ambiguity of her relationship with her father (is he possibly malicious?). I didn't really understand the overall storyline but I felt like it was supposed to have a lot of implied secrets (or maybe I accidentally skipped the opening?).
One of the areas (spoilered discussion about non-game stuff related to one area) (Spoiler - click to show)is a pink hotel in Hawaii, which is fun because I drove by that hotel a lot when I lived in Laie. It really stands out and for me was a big landmark in Hawaii, so I enjoyed seeing that).
This game really hit me in a weird spot because it coincided with an idea of mine in an amusing way.
In my own game, I wanted to come up with something to 'scare' the player, a horrible device so terrible that every player would run in fear, only for it to turn out to be a joke that can be solved in one move.
My device was called 'hideous contraption' and had random dice, twenty six levers, 8 strings corresponding to elements, Towers of hanoi, goat and cabbage, etc.
But it was all a joke.
This game is just like that. But not a joke. The most horrifying thing I could think of a game having, that's what this game is.
After a brief intro, you find yourself in a room with two switches, fives lamps, rope, a ladder that is movable, an exit, a chandelier, a button, a fitting, a track with fire on it, moveable scales, an egg timer, etc.
You have to manipulate all of these devices, plus far more. Oh, and your verbs are extremely limited to 2 or 3 at a time. Oh, and there's a turn limit. Multiple ones, in fact.
I just refused to play it. Hints wouldn't give the full experience for this game, and I just frankly didn't want to play this type of game. I like games where you don't need to take notes, just learning over time.
I said as much to Mike Russo, a tester of this game, and he said it wasn't that bad.
I drew a very extensive diagram of this game, took careful notes, and got 4 or 5 points by being careful and a sixth point by dumb luck. At that point I looked at the hints.
I don't like this game style and don't want to see games like this in the future, but that's my personal opinion and does not necessarily reflect the general populace, and should not be an impediment to future games in this genre. However, I do recognize the craft and polish that went into the game, and the storytelling is exquisitely good given the circumstances.
I played version zeta-3 of this story.
This review is a bit odd to write, as I'm approaching it from two points of view. On one side, this game is a definite artistic statement. The author writes in the overview:
"It's not a game. It's not interactive fiction. It's not a puzzle. It's not action-packed. It's not fun. If you're a gamer, you'll hate it and should not play it. It's not interactive fiction. If you like interactive fiction, you probably won't like it. The reason such people should not play Le Morte D'Arthur is that it violates all the norms of these firmly established genres."
And so as someone who does like interactive fiction and puzzles and action, I have to take that into account. It's essentially like a vegan reviewing a steakhouse, and so as someone not from the target audience, I wouldn't take my feedback to indicate necessary changes.
On the other hand, I also have to see how I feel about the game just as a game, as if I had found it out in the wild, even though it's impossible for me to be completely subjective.
In this game, you play as King Arthur. Most fantastic details have been removed; though I haven't seen it or read it, I'm reminded of the showrunners of Game of Thrones who reportedly stated that they tried to strip as many fantasy elements out of the show as possible, as 'We didn't want to just appeal to that type of fan'. Here, too, it seems like the author has strived to appeal to a broad audience. There is no magic, and the traditional systems of chivalry or witchcraft or even tragic noble love are generally missing here. Instead, the focus is on a life of poverty, sickness, animals, and decay after the exit of Rome.
Play is based on little storylets that happen one right after the other, with a few choices per page of text. The game is very large and mostly cyclical, with Arthur dealing with local disputes, having family discussions or issues, spending time with his dog or nature, fighting the Saxons, and discussing with Merlin in turn. Each of these elements progresses as time goes on.
The discussions with Merlin are a focal point for the author, and seem to be the central thread of the game. They are posed as Socratic dialogues, with Merlin asking you questions, generally correcting you for your mistakes.
Now I'll take about my five criteria for rating IF (which as the intro says, this game isn't designed for standard criteria, but I find it useful as a way to organize my thoughts):
Polish
The game is polished. While it is still being updated and there are some unfinished artwork, it is a very large game and has few issues for its size, and no bugs that I could see. The ending (Spoiler - click to show)has a surprise use of video, which was well done.
Descriptiveness
The game is very descriptive. It depicts a squalid and lawless world, with crude but humble people. It paints a picture of decay and loss, loss of culture from Rome and loss of life and land from the Saxons.
There were a lot of features I wasn't sure whether were historical or not, so I looked it up. For instance, battles tend to have very high casualties, so I looked up how common that was at the time. There is a great deal of rape and sexual interactions with young teenage girls in the first half of the game, so I looked up how common that was. There is a casual disregard for life and a system of slavery, so I looked up about that. Sometimes what I found agreed with the game, and sometime not, but there is a lot up in the air.
The text uses few archaisms but throws in some celtic curses. The language is brusque and casual, with references to farts and diarrhea but also tender family language. There were a few incongruities (one noble uses modern slurs to insult another as a (Spoiler - click to show)pu**y fa**ot).
Interactivity
The storylets are disconnected. Choices from one are generally not brought up later on. Instead (behind the scenes) incremental changes to overall stats are made, like Choice of Games. You need not worry if you make the wrong choice about who should lead a clan or who should be put to death, as it doesn't affect anything later down the road. That's only at first, though; the last 25% of the game has many important choices to make.
The interactivity does feel better as you go along. At first I felt like I could pick anything and it really didn't matter, while near the end it did matter more.
I had a very satisfying ending right until the last screen, where I was more or less informed I had been defeated (the code for my ending was (Spoiler - click to show)defeatresolution. I support being able to 'lose' in long games, but I think it can be done in a more satisfying way. In fact, the ending was pretty great; I think one or two lines might make it more satisfying. It's rough after playing a 6 hour game that takes quite a while to replay to hear 'you played wrong as a player' rather than 'your character made wrong choices', which are two different sentiments, and I'm getting more of the first sentiment.
As an accessibility note on the ending, (Spoiler - click to show)I had difficulty hearing the voice as I was in a public space on a quiet computer without headphones. Having a text transcription or subtitles of both sides of the conversation could be useful, even if it only appears after.
Emotional Impact
I started this game with a bad attitude, and felt justified as the game was often repetitive at the beginning with low stakes in most choices.
But, due to the slow buildup and epic length of the game, I began to know the characters a lot better, from the local doctor/healer to Mordred and others. It made the ending actually quite satisfying emotionally (outside of the very last few lines), and felt like there were real stakes in dealing with betrayals and friendships and loss.
Would I play again?
I might, although it is difficult to say. The game is very long, and the mechanics are more or less intentionally obfuscated. There is no real way to look at options and think, 'What is my strategy here?' Sometimes being bold pays off, sometimes it hurts you. I think that's a great way to introduce real-life ambiguity into a game, which was why I was so surprised to have 'you played right' and 'you played wrong' as endings. With all the micro choices over the course of the game and no indications as to what their effects are, I think there's room for endings that are equally valuable for the player, just varied in the actual results.
Overall, if I had found this game on its own, I would have thought it was a marvelous game. There are parts of it I don't agree with in terms of treatment of women and some language, but I am often an outlier in feelings of that sort and wouldn't base any decisions off of that. Due to that, and to my feelings about the combination of unclear consequences and strongly delineated endings, I'm giving 4 stars out of 5. I think most players who stick it out through the lengthy game will enjoy it, and I would consider it a success and one I can recommend to others in the future as an excellent historical fiction and military story.
This game was real surprise for me. I was looking for something short to play in the French Comp, but this ended up begin quite large.
You are in a bunker during a world problem (something like Covid but bigger, forcing many people underground in bunkers).
The game is split into two sections. The first is a complex computer system with areas like digital libraries, an encyclopedia, archived footage, etc. The second is the bunker itself, which you can explore, including lockers, a library, etc.
The system used is Moiki, and it looks great, with satisfying fonts, click effects, images, and music.
Overall, the story was quite complex. I had to use hints eventually (I didn't realize at first that you can't access later hints without accessing earlier hints). I feel like the ending I received didn't resolve all the narrative threads, but I liked it overall.
This game is a classic in the style of the period between Infocom and Inform. Those few years in the 90s saw the rise of several gigantic indie games, often with obtuse puzzles and nonsensical, Zork-like landscapes. The Unnkulia games were the most popular I know from then, with lots of silly Acme products.
This game seems influenced by the same era, with a lot of ACME products.
You are getting a shopping list for your aunt when you fall down a big hole. There you find a complex web of locations and buildings and teleporters that take you all around a house, a village, and the world.
This is the kind of game that's designed to be played on and off for months, possibly working together with others online and not necessarily designed to actually be solved. Often times the solution to a puzzle is something found far away in a different room.
There are many teleportation devices in the game, including one powered by geometric objects, another with different button presses, and another in the form of a wand. A lot of puzzles are coded messages, as well.
I played this game to clear it off my wishlist as one of the longest-running games on that list, but was surprised to see that this author is the same Jim MacBrayne that has recently released games in IFComp and Parsercomp. Those games are written with a Basic engine (and I think there is a version of this game that does that too), and they have very similar features to this game, including giant maps with many rooms called 'corridor' or 'path', and puzzles involving color-coded combinations and obtuse messages that must be interpreted correctly to pass.
I know several people have greatly enjoyed these recent games from Jim MacBrayne; if you're one of them, this older game has a lot of the same flavor, just longer and more difficult.
