Good game, and interesting concept.
First off, let me say that I liked how it just jumped straight into the game. It gives you a feeling of uncertainty, which is nice for games like this where you have to watch yourself or you'll die. I also liked how well hidden the traps were. They actually made me think about where they might have been, and I found myself squinting at the screen in observation a number of times. The ending was also very well conceived, and unexpected.
On the downside, game mechanics were a bit flimsy when it came to the character movements, but with only 96 hours, the quality is definitely up to par. Also, I really wish the signs said something, even if it was just cryptic nonsense. It would have really added to the atmosphere.
All in all, a challenging game that will keep you guessing. Well done. :)
