First I thought I couldn't move, but the movement is just a bit strange. Are the shapes around the player just the default collision shapes, because they feel a bit out of place. The Idea with being able to fly in exchange for a bigger hurtbox is interesting, but there is very little actually game that uses it. Overall it just needs a lot more polish like better visualization, sounds and level design. I can see a base for a game here, but not sure if the core idea works.
Yea, the fluff behind the shapes is that it's an indication of how much magic you're leaking out / the detection range of the enemies.
The misplacement is deliberate - making it possible to 'brush against' the enemy circle made it feel fairer and look a little less janky.
Maybe I'll add the missing features and brush it up in the future.
Thanks for the feedback!
