oh yeah, this is a good concept. The SFX were really good. The only thing that would have made it perfect really is if you don't reset the boss HP every time you get hit by a leaf. For a jam I think just make it easier like just slow down every time you get hit by a leaf. Maybe show the fade out of dying, but let the player keep playing until the boss dies and then show the ending. Maybe focus on that like show the ending even for a jam. Overall great job though, very good!
