Amazing job! Artstyle is fire, idea is fire, difficulty is fire. Only part I didn't like is the mana system, I think it could be removed and the game would in my opinion be better.
Thanks for the feedback! 100% agree on the mana system. I did it to avoid spamming but I should've found a more fun solution rather than just adding a "limit" (lazy design). If I continue it in the future, that is definetly something I'm changing!
