The tune is super catchy and It's nice that you've made quite a variety of levels, but there are some game/level design things that could be improved. If you start each level going to a different side and already being chased - for instance - the player will always fail at its first attempt on that stage.
Also, sometimes the game just freezes when you retry a level and I had to refresh the page.
Anyway, it was a fun game and I played almost all the stages :) keep it up!
