The atmosphere is really good, I liked the ambient sound! Felt kinda like FNAF a bit to me, but the note stamping gave me "All work and no play makes Jack a dull boy" vibes from the Shining which I thought was pretty neat! I do think a quick tutorial would be a nice touch but tutorials are hard on game jams given the time constraint. I also think I got the game breaking bug you were talking about in the comments, but other than those things this was really great!
