Really good game over all. First I want to say I absolutely love the art, and music. It really gives a retro vibe. Secondly using physics to move is a genius mechanic, and as a physics junkie myself I quite enjoyed it. However it got a bit too chaotic after the first level, as I kept losing track of the object. The object reestablishing every few levels would be a nice touch. But other than that I really love this feature concept. It would be nice to see it expanded upon.
