Very nice! The cutscenes and the overworld map were nice touches. I also really like how much variety there is in the levels, for better and for worse. The auto-scrollers, the guided maze, the boss fight, they were really fun. But the math question and the unlit maze were more annoying than fun. It was also annoying that the animations didn't reset with the slide, as a few of them were on a really long loop that lead to a lot of waiting. But otherwise, it's a really fun game.
PS I'm sorry if you got three messages from me, my comment got posted a bunch of times for some reason.
