Taking a preexisting game and reversing the roles is an interesting idea, but I don't think it works in this case. Some levels feel impossible and others are a cake walk. The physics don't feel quite right and it's annoying having to watch the little drawing animation play at the start of every level. The music is nice and the presentation, while simple, gets the job done. With a bit of re-balancing and tweaking of the core systems, this has the potential to be a fun game.
