I enjoyed my time with this game. I wasn't sure what to expect with what looked like pretty simple art on the surface, but during gameplay I really appreciated the stripped down style so I could focus on the attack patterns and movement. And in the moment-to-moment play, I think the clean art really shines more. I think it was smart to give players the new ability after battle instead of overwhelming them all at once.
The reflect mechanic felt a little off to me, like the hitbox was effective on my sides, but not in front of me, so I found myself just side-stepping attacks to hit them with the reflect instead of attempting a traditional type of parry.
Overall, I thought this was a great jam game and ambitious with so many different bosses. Good work.
