Pretty good. I too got the bug that was mentioned by Gatlink. It's happening when you are holding a movement key and hit space to mutate the turtle. Playing as a hockey puck to kill enemies was a fun idea and I wish you had more time to explore it. I liked the little story bit at the beginning but you need a way to skip it after you've seen it once. I was able to get through several rooms and I think you did a good job of ramping up the difficulty. I wasn't able to make it all the way through as I keep accidently hitting the stuck walking bug and needing to start over. Overall neat game concept I think you just needed more time (running out of time in a game jam?! *gasp* :-p). Thanks for the game!
