Very cool concept. The difficulty started out too much, wasn't hard once you got the hang of it, but it would have been nice to have an easy level to practice on at the beginning. The background made seeing some obstacles difficult (especially ones you have to slide under) but I kind of suspect that's what you were going for. Cloud level 4 I cannot get past because one of the obstacles I need to slide under she just keeps sliding until she falls, much farther than a normal slide, and due to previous obstacles there is not enough power for a double jump. Maybe I'm just missing something but I've tried several different ways around it.
