Pretty good! I think the movement was a little too fast, which made the precision platforming a tiny bit frustrating, but overall it seems well polished.
The audio was good, the graphics are nice and simple, and the particle effects add a nice little "oomph" to the whole thing. In terms of the theme interpretation and implementation, it's a little standard as I've seen a lot of other games in this jam so far implement it the exact same way, but that's okay!
Nice work overall!
