Cool concept, I really enjoy arena style fighting games !
However I found the controlls very counterintuitive, I did need 3 tries to understand how to use the spells XD
I either wasnt sure if the spell is already equipped or while equipping it I was (unintentionally) holding the grip button and when I wanted to cast the spell I released it and the spell just fell onto the floor ^^
After some tries I got the hang of it but it was not that easy to aim for the other wizards.
Cool VFX and with some improved controls this could be really fun !
Nice job !
