Really like the spooky aesthetic of it and the audio is great. I agree with GalloPinto's comment on using up and down when on the walls being more intuitive as that's what my hands would try to do without me thinking whenever I got invested, haha! Puzzles are great and love that there are multiple solutions. If I had to give any critique, I'd say give the player the tiniest bit more time to get comfortable with one mechanic/enemy before introducing a new one. Overall, great experience!
