Hello Hungover Sunshine, thanks for the kind review!
I agree with the point you made, the Supranova spell ends up being less useful considering its cost, it's something I'll definitely rework after the jam
Unfortunately, I noticed that it got difficult to reach the boss room, a tip I can give if you play again in the future is to use fewer enemy killing spells and focus on running away from them (stun, invisibility, dash), since they usually give up after a certain point, except for the explosive rat.
Again, thank you very much, it's great to read such detailed reviews 🙂
