This is a pretty cool game! I like the visual design a lot, and the gameplay is good. I found it to be fairly difficult, but not unfair.
If I had any critique (and this is minor) it's that the controls don't feel quite "perfect" yet. I can't quite explain it exactly... they just didn't feel as smooth as I would have liked I guess. But this is less a big problem, and more something I'd like to see polished if you plan to continue development beyond the jam!
Overall, really nice work! Keep it up :)
