I loved playing your game.
I think the soundtrack is really nice and fits the style. I also like how you make this almost more of a puzzle game than a platform game by giving you just enough HP to cast spells to clear the level. The animations look amazing and the levels are also really nice.
I would like to know how many Zackavelli's there are though, a counter for example would help. Because let's be honest, no Zackavelli deserves to be locked up in a cage!
Looking forward to your games in upcoming jams!
