There's a lot of cool things here. The little tutorial, the level manager, end credits, sound effects, cute music, star achievements. Feels pretty fleshed out. I would say the transitions are a tad too slow, I would speed them up a bit (for things like the 3 star achievements, level manager). Is it possible to get lower than 3 stars? I didn't feel like the move limitation was limiting at all, I never needed to retry a level to figure out the best path possible so I would maybe tweak that a little to make it a bit more challenging. Otherwise, great job! :)
