Good, addictive
Graphics - They're nice and detailed enough. easy to see what's what and stuff.
Style - Sneaking made MGS a good game, and puzzles are good to make you think. would be nice if you could move diagonally aswell, but it's not a big problem.
Sound - Not much sound except the music which gets a little annoying. But I kinda started to ignore the music after a while. It's not a kind of music that you can't ignore and it's always annoying you the whole time. Kinda atmospheric.
Violence - some blood and beating up at the start movie. I dunno what happens at the end yet, 'coz I'm currently stuck on 26, but good so far.
Interactivity - running, hiding, and pushing. The puzzles work well, and so does the interactivity of the whole game really.
Humor - Gotta love running around in a box!
Overall - Well made, not too much of anything so that it gets boring, because all the rooms are different. The puzzles are well made. The game is addictive. A walkthrough would be nice, please :P I'll work it out eventually..
