I love the idea behind this. The gif showing a later level seems really cool. I see that there are some good physics running to go along with it, and the sprite work is good. Unfortunately, and I recognize that you only had a little while to make the game, but I didn't really understand what to do. It was hard to exit the game, and the character wandered offscreen on the first "level" and didn't ever come back. I don't know if it was supposed to do that? The objective of the game was also unclear.
It definitely fits the theme of the challenge, and the idea is awesome.
