I love the music! It's soooo calming. The mechanics of the game fit so well with the theme too. It really made me enjoy the atmosphere of the game more :D
I think the movement mechanics of the witch and cat could be more obvious though. It took me a while to realize the witch and cat could wall jump, I kept trying to jump on top of each other until something happened lol
Also, maybe you could make the cat and witch disconnection more obvious? I know you did the cat eyes thing, but some other indicators like a "powering down" sound effect or something would make it more obvious
Good game overall! :D
