I guess I'm dumb. Couldn't figure out what to do with the cheese. Put it in front of the hole, nothing. Made it different sizes... nope. I get the core idea as a puzzler but the overall gameplay was good. Smooth controls and good graphic elements. I didn't care for the whole level being that greenish hue after I got the spell. Well, maybe not the whole level but the light source changing to green wasn't my favorite.
