About the Story

Get to the treasure before Mobile Support kicks in

From the ZROK: The Great Underground Impaler game blurb:

Experience the latest in Artificial Incompetence technology right in your browser! This game has it all: treasure, monsters to attack or bargain with, items to pick up or drop, and doors to open as you enter abandoned properties at your leisure.

The game features our latest UI technology! Experience fully automated customization of font shapes and sizes. No more fiddling with game settings, the game takes care of it all! Now, you only need to get to the treasure before our advanced Mobile Support kicks in.

NOTE: My game uses a canvas element to draw the "parser game input/output" on the screen. It also makes use of timed text to emulate the "terminal I/O" and occasionally for dramatic effect. All of this won't work with screen readers. If you rely on screen reader technology, you may want to look at other IFComp entries instead.

I do try to be inclusive and I have therefore added a screen reader support toggle (currently in beta) in the options dialog reachable from the main menu. When screen reader support is enabled, the parser game text will be merged with the commentary by Roger and Wilco, and all timers will be disabled, thus producing a single page which can be read out by a screen reader. Feel free to try it out, and let me know how it works out for you.

Short parody of Zork in a technical showcase wrapper, September 4, 2025

On first starting this game, I was strongly reminded of Rover's Day Out, due to the split-level reality of the action taking place. However, as play continued my thoughts turned more to the early chapters of Homestuck.

The minimal challenge to be found in Moon Logic comes primarily from dealing with the "helpful" automation that attempts to interpret what the player means to do based purely on the chosen verb and the object context. As one might guess, this is only sometimes what the player actually wants to do. Soon enough, anyone playing this will be learning how the automation thinks and trying to anticipate its foibles to accomplish one's objective.

The main action involves exploring the immediate environs of Zork's classic white house. It's an impressive bit of work, both looking and feeling like you are interacting with a world model engine as complex as would be found in a typical parser game. (There's even nested inventory!) I find myself very curious about the technical underpinnings of this work and hope that author Onno Brouwer will provide some details in a post-mortem after the competition.

The player familiar with the original on which this spoof is based will recognize the NPCs and locations, often modified from their inspiration. Although the setting and emulated display strongly encourage the sense of playing the original, actual gameplay frequently diverges from expectations. Perhaps the greatest feat accomplished by Brouwer in this work is creating something fresh that is also a parody of Infocom's first game.

Along with the main progression of plot action, there is a second progression involving the UI itself. Billed as featuring the latest in "artificial incompetence," the simulated game proceeds to live up to that moniker by imposing visual effects over the basic text window. At first, these are fun and amusing, but by the time it gets to the point where (Spoiler - click to show)the text orientation rotates every few seconds, I was looking for the off button. (Fortunately, Brouwer has provided one.)

At the end, the game delivers a ranking in the old school style -- one based not on points but on turn count. Presumably, fewer moves results in better rankings; if not, then the ranking I received (Spoiler - click to show)("'Me, too' adventurer") is a bit of metacommentary. Achievements are also tracked, pegged to turn count instead of point value, making me wonder whether there may be more to be found than I saw in a single playthrough.

This isn't a deep game, but it is a fun short experience that mixes a bit of potential nostalgia with a demonstration that much more is possible in today's technical environment. It's well worth the time to play.

Choice-based Zork parody with unusually constrained commands, September 25, 2025
Related reviews: about 1 hour

Someone in my life dislikes cheese, pickles, and mustard.

If I spent a long time making a beautiful cheese-filled pickle dipped in mustard and presented it to him, what would be the desired reaction?

This game is a kind of Mystery Science Theatre 3000 version of a Zork knock-off. On the left side, it has text resembling a parser game. On the right side, it has running commentary by two people playing the game. The only way to control it is through a bar of commands at the bottom.

The game also seems to have taken a wide slew of complaints about interactive fiction games and put them into a game to make it as irritating as possible. And I do mean intentionally; the author is quite aware of the frustration involved, from the name 'moon logic' to in-game comments.

The game uses timed text, a famously hated IF concept, and uses it in a way that doesn't contribute to the game meaningfully. It has a 'fast' text setting which is still fairly slow. The pseudo-parser text is not scrollable and doesn't have a back button. It later on adds shaky text effects, zooming in and out effects and rotating effects. These can be turned off.

The menu is intentionally obfuscated and basically turns the whole game into a giant tower of hanoi problem, reiterating smaller solutions in the same order over and over to recreate even basic tasks. Only 4 or so commands appear at once but disappear as you use them, so to get to important commands you have to repeat a ritual of examining, looking, and inventory. There is no choice on where to go, only a 'go' option, so you have to limit yourself by closing exits and such to move around. You can only take and drop items in a very specific order.

I felt my left eyelid twitching by the time I was done (I was also playing Violent Delights at the same time, a game that asks you to wait for a long time while playing).

So, this is a game where I recognize the craftmanship and creativity but did not experience joy through play, much like Targhairm. It is clear that great talent and work went into it, and the puzzle logic is quite complex and parts of figuring out what to do next was enjoyable, but the apparent goal of frustrating and bedeviling the player was also achieved.

Edit:
I should mention that it looks like I missed some features in Moon Logic like screen reader support which helps ameliorate some of the more frustrating aspects and lets you pick between the 'frustration' version and a version that lets you focus more on the clever puzzles. I did eventually figure out the UI features at one point but I recommend trying the screen reader support both on and off to see what you prefer.
