Great platformer (which is kinda funny, considering the premise) game! Reminded me of Super Meat Boy, because of the pleasing visuals and silky smooth controls, which are very responsive.
The concept might be predictable, but gameplay wise you made it very interesting! As others pointed out, the music sounds odd at times and audio mixing could use some work, but it's not that big a deal, in my opinion.
Still, you layed out a pretty solid foundation for a full game, great job!
