First of all, wow, someone is a fantastic artist! The art was stunning and absolutely beautiful really can't fault that. It was short but sweet - perfect for a game jam game and it just felt really polished.
I do feel like there were some missing sound effects that could be added since they were noticeably repetitive. But that is a teeny tiny speck of feedback on a really great submission.
Final thought, and this might just be me, but I felt like it was missing a sort of "bounce" upward each time you hit an enemy - almost smash bros style. I feel like bouncing between enemies hitting them in mid air was where the gameplay really flourished and so if you could sort of keep up air time I think it would feel super satisfying for an otherwise quite simple combat mechanic.
Really fantastic entry though. Absolutely incredible job.
