I liked the writing and when I reached the 3 door I started to feel a little spooked. even though I'm not sure why I should be scared. It would make sense to lean into the insanity. Maybe with a Cthulhu like entity lurking in the shadows. More then then the lighting and level design and I'd say the sound is what really sold the atmosphere.
The idea of turning in circles to change what you see was interesting although I didn't even realize it was a thing until the chest puzzle. And to be honest it didn't feel like a puzzle. It just felt like I was turning in random directions until it worked. The only "puzzle" that was clever was the one where you need to walk backwards to get out of. But even that felt like a cheese.
And sadly by the end I was starting to feel sick. I'm not sure how you would fix this but it would be worth while to look into. Or maybe I just have a weak stomach. lol
All in all I'd say this was a good game. And bonus points for Linux support. I would like to feature this game in a game jam review video for my YT channel. Thanks!
