I'm getting the same issue when using Chrome. In Firefox, it worked for me though, did you try using another browser?
BTW, I got a kick out of all the different "death" animations. It's pretty funny. Are you supposed to be able to jump mid air over and over again? I played an entire game where I just tried to see if there was a limit to the number of times I could jump in the air without touching the ground and made it like 10 times before running into a speaker.
