Wow! This is so professional... I wouldn't have guessed that it's a game jam entry, just a demo. There are even animated menus and a variety of settings O.o
I love when games tackle psychological themes as I would say they are the best medium for that.
The visuals are great, so is sound design. I also like the little text animations.
Really amazing atmosphere overall, genuinely scary. I very much enjoyed it, great job!
