I subscribe GosuKitta's comment. It's a very interesting concept, it's just that it looks messy. And I don't know if it's just me, but I can't survive for too long, it's too hard. But it's a great entry for a 12h jam in my opinion.

cool

The mechanics are there, and they look very interesting :) the graphics ruin if for me though... its so messy. I like that you made animations for everything and it really makes the game feel alive. No sound kind-of sucks.. even basic *pew pew* sounds made with your mouth would have been fine for the 12h jam hehehe. Good try though, hope you have learned a lot making this :)
