For a platformer, not bad. The art was pretty good. The controls felt pretty good but the jump felt more like low gravity and you couldn't move after jumping but I assume that's intentional? The confusing thing for me was the background kept confusing me into thinking it was part of the platform. Parallax would have worked great there. That aside, I was enjoying it. Not sure where I was supposed to go so I ended up running off the map. The far right border didn't stop me. :( Given the constraints though, I thought it was interesting, though buggy.
