That was an awesome experience! Port that to mobile, I'd play like crazy!
My only feedback is that Level 13 was a bit frustrating because of the narrow corridors, I kept sticking to walls trying to go fast. Other than that I had a blast playing. Nice little animation at the end after you beat Level 15 :D
Nice and juicy game. This game shows that you don't need crazy graphics to be fun! GG on your game!
