Awesome game.
But there's one thing that Really bothered me. I was playing the game with the thought of survival and only survival. This worked great, until I got to day 10, thinking "Well, it's been great. Too bad it's over already.", when all of the sudden, a giant worm come out of nowhere and kills me several times. I would have been great if you had, say, put a "You see a huge presence under / coming toward you. And it looks hostile." in the introduction. That's about all I can find wrong. Other that that, this is one of the best damn games I've played on the internet.
