Some good graphics for this one! Love the Death sprite.
I also really like the combat as it is - dashing around to dodge and hitting inbetween. Invisibility is useful too. And each witch has their own attacks to look out for.
I just wonder why there's so much space between each battle. You look for the witch, kill them, and then have to go back.
I think the game would be neat even in less space - more like an arena boss battle for each witch showcasing their spells. Because as I said, the combat felt real nice, maybe centering the game even more around it would be cool for a sequel or something.
Besides that, great entry! I had fun playing it.
