Very fun game. It was quite addictive.
I honestly don't have much major feedback, the art style might be a little too simplistic but I also think it is part of the charm.
One thing I did notice was that when I used that sword ability on the wizard orc while he was casting the fireball that he throws at you, it disappears mid way through since I believe it is a child of the enemy entity. It might be intended but it looks a little rough since it vanishes immediately.
Good job nonetheless.
