Great job! I love the artstyle and the idea is original. In fact, I haven't heard that idiom before. The game itself was fun for a little, but it gets repetitive. And for someone who doesn't care all that much about getting all the stars it was rather easy. I think to expand this game, you could implement more mechanics involving the environment, perhaps make it more into a puzzle, where you are very limited in the number of moves. Right now the interactions with the environment are rather flat. Bounce pads or portals could be interesting. I found myself trying to use the wall to bounce in the first level, but found I couldn't.
