Super fun and unique! It really surprised me. I like how you play with gravity. One small suggestion is that in the "more!!!" level, the background and the obstacles have similar tone of colour. I made me think is that an obstacle when I first play the level. I wish the contrast between the two could be stronger.
Overall this is a very good game. I could play it for a long time. I think you should consider to design more levels and publish it to bigger platforms.
