Hey! Did you make the player sprite yourself? I really like multidirectional sprites like that, but animating those is a big pain in the butt.
Anyways, I like the game and think you had a really fun idea. I appreciate the little tutorial in the beggining. My main feedback would be just having the spell whell use the mouse to select spells instead of WASD, as it was very difficult to shoot and avoid enemies at the same time. Maybe lowering the speed of everything a little bit would help too.
Overall, great work! if you are new to making games, keep at it! It is a super rewarding experience :)
