Very interesting game! I included it in my compilation video series of all the games entered in the GameMaker Studio 2 Beta Jam #2, if you'd like to take a look :)

This was cool, played it through to the end! Was stuck for a long time against the wizard in the bottom left but the regen spell let me overcome the pesky mirror spell.

Some potential here for sure, I would perhaps adjust the speed at which players can move between the menu of spells and then take stock of which spells are providing the most interesting relationships and see how you could create more situations like that.

Good job!
