The game was very charming, and I love the inspirations drawn from Hollow knight (I mean just look at those wings and the sword!)
In terms of sticking to the theme, I feel like it made some of the gameplay kind of frustrating (notably the dash being very unreliable as a tool). I think thematically the idea of the magician losing control and going from having some spells to not having them altogether would have made some levels feel less like I'm fighting against luck to win. That's the only real criticism I have.
All things considered I really enjoyed the game and I think if not for that tiny mechanic (or more clever implementation perhaps) this would've been even more fun!
