I like the core idea of this game, as it's quite simple and straightforward, but I think it could use some more balancing for difficulty. Also, it would be great if I had a goal other than "don't die", which seems inevitable whether I stay in one place and watch the Fatigue meter rapidly climb or for some reason I "trip" over something I can't even see and die.
Don't get me wrong, I love difficult games and survival games, but they only work when it actually seems possible that you can survive. You did a great job with the audio and visuals, so I'd love to enjoy that stuff in a game that's not just a death trap. :)
