Genuinely awesome entry!
Impressive amount of levels for a jam entry, definitely eye-catching design and animations - the character is excellently polished! The music is good and the SFX are cool (and every enemy has their own SFX which is again, impressive). Each level has a distinct and clear colour palette which results in the game looking great! The camera effects are excellent, and give the game a lot more impact/oomph. Good stuff. Difficulty scaling throughout the levels felt good as well.
Criticism-wise... the enemies are not really well synced with the music, I felt that especially in level 2. It often felt more like button-mashing rather than well-timed strikes, which detracted from the experience :/ The accuracy and rank rating was a great touch (got at least 95%, and S on all levels with button mashing though, so that's a bit of a shame)
