Really interesting and unique mechanic and I don't think I've seen anything like this. The idea of manifesting balls to launch yourself and attack is just comically funny. The boss itself is kinda tough due to the absurd amount of health it has and me having skill issue. I do want to suggest that you make the mana regen and consumption more prominent and smooth, so the player can have an easier time manage their resource.

Thank you for the feedback. The boss health should've been set lower. I tried to put it at a level that I found challenging but since I've been play testing the game all weekend probably isn't the best way to do it. I didn't realise the mana bar was a problem. It definitely needs improvement. Thanks for pointing it out.
