Great game! Cute art style and good looking animations. Good music, and fun and challenging gameplay. There are a couple of things I think that could make the user experience better: boss health bars, some iframes so you cant get hit by the same projectile twice or two projectiles/enemies ontop of each other, a sfx to let the player know if a fireball projectile hit, and some more in game info at least the first time you exchange abilities (about what it means and how it works). Overall it was a ton of fun to play, good job!
