there were really interesting mechanics here I liked most of them, but they all look cool.
the hitboxes for the skull and the player probably need some tweaking, but I played a fair bit, and it is doable.
I think the abilities are awesome looking and the visuals with the lights and the way you incorporated it was awesome
maybe making the crow spell reusable and maybe adding a spell for environmental protection would be nice too you just have to figure out a way to limit them
overall, a very cool looking game
