This is really useful feedback - thanks so much!
I'm hoping to work on my puzzle design, as I tend to default to just "find the keys", but I think these sorts of games really benefit from more involved ideas, particularly if they link in to the themes. Time for me to go back and replay a bunch of horror games for ideas!
Inventory audio is a great point, I'll aim to patch this in after the jam as you're absolutely right that it'd improve the feel a lot. I'll try and get the odd issue with misalignment as you scroll through too, as this has been bothering me for a while.
Delighted I was able to scare you! Always makes me happy :)
