The bugfixed version seems to work perfectly, so I was able to play it now. I really like the artstyle, especially during the cutscenes. And the gameplay was amazing, super satisfying to hit enemies! I really like how impactful each hit was. The boss attacks also felt powerful with their screen shake. Good job!
I was just confused about how the low HP mechanic works, it seems that you go into a mode where you do more damage and heal back your life if you defeat enemies? I'd add a tutorial in-game if possible. Nothing much, just a small tidbit of text telling you the basic controls and mechanics! I went to the game page to find the controls, but during the jam I play most games from the jam rating page, which does allow you to download files but does not show you the game description.
But this is a very minor complaint, despite the length of the paragraph. Overall a very solid submission!
Edit: It's a jam game, so I know the constraints. But if you ever wanted to improve it further, adding more moves would be my priority. Do you have plans to continue it?
