A great, bite-sized Metroidvania. Does just about everything well: logical, smartly compact map design, tight control, fluid animation, good character design, and mostly great music. The Ikaruga-like gimmick of alternating between wind and fire elements is novel for the genre and is very satisfying in boss fights. Leveling doesn't feel very impactful, but it's not difficult enough to warrant wanting to grind, and it's probably all the better for it anyway.
