I loved the idea, thought the game was well polished (the jump is amazing, even if a bit slippery), but I really disliked your levels. I think blocking the player so they have to restart using the R key (which I don't remember you explaining btw) is really really frustrating, even more so when it is not necessary - like in the third level where you made the platform to go up red, which means if you fall while red you can't get back up. After falling two times I just gave up.
Edit: I forgot to say I really liked the intro too, it was funny and I didn't feel like I wanted to skip it :D
