This is fun, followed your instructions to play all four levels. It felt a little unintuitive that, say, if i was moving left that switching gravity to up would just stop me. I don't know how you'd justify it but I feel like having vertical and horizontal gravity both always in effect could be an interesting way to make sure you're going out of control everywhere, but maybe that would make things too hard. I do think the sound effect for hitting the wall was a little grating, but I definitely enjoyed this!
