This adventure seems like a straight up good time! Every room has something strange about it and once players figure out the pattern, going room to room becomes its own little minigame. The chances of finding Holly increase as the adventure progresses, which is nice. Solid hooks, multiple conclusions. Puts the fun in funhouse dungeon.
One typo that may (or may not) have an effect: The Office (Room 12) lists the quail as its anchor. Based on context, I think you meant quill. A quail is a small bird, a quill is a feather you would use to write. HOWEVER, I think it is wayyy funnier if players need to find a quail who can dip its beak in the inkwell and transcribe your words. After the jam, I'm not really sure whether you should fix it or not...
