The graphics are amazing! The idea is also very intersting, you have to balance 4 stats at once rather than only managing your health as usual. Also having to choose the difficulty of your enemies and getting a preview of what they will do with also certain abilities that activate only after a certain stars treshold, and others that scale with the more stars you have, brilliant!
I could honestly see this developed further, maybe adding some roguelike features.
Honestly impressed, congrats!
