Great! I love the character animation, ambiance and art.
I don't have too much to add besides what people have said below, but here's what I've got:
- The environment feels slightly too big and hard to navigate without a map
- The character feels somewhat floaty, but it works well enough
- the 1st eyeball boss was hard to predict, mostly because it seemed there wasn't a pattern to the attacks
- (can't remember if the boss had unique music, but could be cool if not)
