Totally awesome! Sound and music were amazing, and the world you've created is crazy! I really liked all the small effects, like the distortion on the edge of the screen and the wavy speech text, even the health UI looked really cool. And that berry-eating animation! I feel the same way as everybody else here about how cool it was! The only real issue I ran into was that sometimes one of the crabs would walk into the floor if it was on a step below me, and it could damage me without me knowing it was there. You could still kill it, but I don't think these crabs are the burrowing kind :P
I'm a little confused by what the big eyeball guy said... so I get all this money for killing crabs from his crab army, but he's ok with that and rewards me with the bubble of doom? I mean I'M ok with that but I bet the crabs would be upset if they knew it. Great job!
