I enjoyed this game! The art-style is pretty cute, the music is mysterious and fitting. It took me a bit to realise that -  of course - ghosts can move through walls :)

I think you got the mechanic done well and the keys used for it were well chosen.

One thing: Did you forget to set the output rescaling? The game is tiny, I think you forgot to set it to rendering 4x in size.

Good job on submitting, congrats!

I really like this game :3 It's fun and cute!
