Okay so I'm going to just write my thoughts down as they happen here and post when I'm done playing.
The fog seems to get messed up when you move the camera. That probably means it is tied to the camera instead of the game world, which is a little unfortunate. It goes back to its original shape when you stop moving but it is awfully distracting.
OH! You get a little ceremonial dagger that doesn't break but doesn't do much damage. That's at least something. Although... Apparently you can only use it in the "otherworld." The otherworld is kind of interesting, but it's definitely not like the the other SH otherworlds where it is the same exact place you're in but twisted. It's another realm entirely.
The puzzles are pretty interesting so far. I like the item examining system, it's pretty dynamic and actually has a lot of use unlike some games where it's just more for flavor.
The notes are pretty interesting as well, they give a lot of important context to what is going on and allude to more.
There seem to be some lighting bugs where some light sources only spawn in when they are extremely close to the camera. I'm playing at high-very high settings so it's not related to that I don't think. They seem to be static, specifically placed lights.
Had a bit of a stupid encounter with an enemy in a ridiculously tight hallway. They were lying on the floor, obviously alive but not moving, but I couldn't attack. Then they disappeared once I left the room. Then I did something in the next room over and of course then they spawned in that same room. Seemed kind of cheap to just spawn an enemy in that kind of way. At least have it crawl through the window or something.
Speaking of the enemies, they are no slouch BTW. They will follow you to the ends of the earth as long as they can still see/hear you. They will jump up to higher ledges and everything. It does make them feel more dynamic.
