Everyone is, i think, familiar with the genre of "one move" games, originated by Aisle and followed up on by titles such as Pick Up the Phone Booth and Aisle and 50 Shades of Jilting.
Unlike most such games, this one has a puzzle. You have one move to act. That action, all by itself, a single command, has to completely solve the puzzle.
The puzzle.
That damnable puzzle.
The evil, insidious, dastardly, cruel, vicious, mean, demonic ... incredibly interactive, deeply implemented puzzle.
I mean, I found my experience with this game to be one of incredible frustration, but it was the kind of frustration where the parser is being perfectly responsive and the reactions to your actions make perfect sense and you always feel like you're this close to the solution when, in fact, you're still another fifty iterations away.
Five stars for That Damnable Puzzle. One star deducted because something important isn't made sufficiently clear: (Spoiler - click to show)the event isn't always exactly the same, and the differences are of paramount importance.
Absolutely not recommended for beginners or inexperienced players. For all that there's only a single command required, I rank this with some of the hardest IF I've ever played.
(this is a review of the original game, not the remastered Steam version)
now, i'm not the type who tends to get through games without resorting to at least a FEW hints and walkthroughs. there are different kinds of puzzles that a person can get stuck on. sometimes a verb must be guessed. sometimes there were non-obvious inventory items that were missed. sometimes a game is unfair. and sometimes puzzles are completely logical and even intuitive. there's really nothing like the feeling of being stuck on a puzzle for a couple of hours or overnight and then suddenly having the light dawn: you try it, and it works.
Anchorhead gave me that last feeling many, many times.
i believe i only had to resort to hints a couple of times -- once early on when i was having trouble tripping a specific flag to advance the day, and the later sequence (Spoiler - click to show)in the mill that many had problems with.
more to the point, the horrifying story kept me riveted. there are games where one kind of trundles along, hits a puzzle where any progress seems impossible, and gives up (frequently because the author put their e-mail address under HINTS instead of giving a link to actual hints or a walkthrough on their webpage). but there are games where you hit a brick wall puzzle -- in this case, (Spoiler - click to show)sabotaging the summoning at the lighthouse -- but you're so committed to the character and so immersed in the world that giving up is simply not an option.
i solved that puzzle myself. and it was the greatest feeling.
that said, there are some things that bear warning about and could potentially trigger people's PTSD. the plot relies heavily on (Spoiler - click to show)the villain's history of incestuous rape and, while figuring that out yourself is a wonderful puzzle that gives you that slow, creeping sense of dread as you realize what's been going on, people who've gone through the real-world equivalent may not react well.
the premise is simple: you're a ghost, you were murdered mysteriously, and by going through the minds of the suspects you're able to unearth memories that will either clear them or convict them. the central mystery is very well-crafted; all six suspects are viable and most are interesting characters in and of themselves.
i do regret one thing, though. while the protagonist is obviously tightly focused on figuring out who just killed them, there are things he's clearly not aware of that it's possible to infer from the "red herring" evidence. while i would definitely not call the suspects' relationships "mysteries" -- honestly they're none of the protagonist's business -- since they are presented to the reader, it does feel sort of disappointing that there's no apparent way to confirm them.
it's also the case that i solved the mystery much more easily than i was expecting to just by following the obvious breadcrumbs. i felt like i was just getting warmed up when it was over. of course, "there wasn't enough of it" doesn't really count as a negative, does it?
