I'm not sure it's even a game. It's called a walking simulator, but I'm not sure that's even a fair description, because while it doesn't have puzzles, it doesn't have any freedom either. You might be able to move a little bit around (though frequently you can't), you really just have to hunt for the spot where you can interact with, press your mouse and the story continues (and there's never really multiple places you can interact at the same time). This is as on rail as a game can get. Also, the whole thing is a little over 2 hours long.
OK, so the gameplay is non-existent. What are we left with? Well, the music is very, very good, I'll give it that. The graphics are fine (they don't look bad, but they don't look great, either), though the wobbling as you move is a little motion-sickness inducing. There are effects that are designed to make it interesting and more cinematic, I guess. For example there are time cuts, where you might be walking in a corridor one second and the next you're walking down the stairs and then a few seconds later it jumps to you at a computer. And there are a number of flashbacks and dream sequences, etc. It makes me think the director was a little overzealous in the effects department (it especially seems weird if you decide to start walking backwards and a jump happens... ), but it does give it a cinematic feel of say, something like the X-files (there are certainly some things that remind me of the X-Files, like..
Also, there was one glitch. I was walking into a room, and then suddenly (as if I had fallen), I was inside a closed bathroom (in which I couldn't interact with anything). Replaying the scene made the glitch go away.
If you like The X-files (or Twin Peaks - I haven't seen watched that, but from what I know of it, it would be another comparable one) and you see this on sale for a few bucks, I'd recommend it with the reservation that 1. it's not really a game and 2. unless you're better at understanding symbolism than I am, there will probably be a bunch of stuff that will go over your head.
