Banger idea. The visuals have a lot of juice and are nice to look at, the tutorial and boss intros are very charming, and it's a good time all around. The final boss, specifically the second phase, uses the health bar gimmick in an interesting way I think (though the fight itself was a little frustrating, partly because I didn't find only dodging and not attacking as fun, plus it was pretty difficult), but I feel felt like for the earlier fights the mechanic is not very meaningful, I kinda just played them normally and if I was doing too well just waited for an attack to take damage on. They're still fun fights though with a solid difficulty curve. Also I really like the little jump you do when you land an attack, it's funny and makes timing your hits more interesting
