Absolutely beautiful ! Love the way this game looks, and the character design is so cute I love it.
An interesting idea with a nice story behind it, but will be hard to implement in practice. Maybe having some kind of magic barrier that only protects against powerful magic entities would make sense, Letting you through when you get rid of your powers. Or taking magic abilities away from the player but giving physical means to replace them, changing the character from a magical combat character to a physical platforming one (with wall climbs, grappling hook and such). Also one ability I can see this character have is hovering over gaps.
But apart from my thirst for game design, nice job and I hope you'll be participating in the super edition to see more of this game !
