There's just not a whole lot here. The environment is quite nice but way too dark and there's just not a whole lot of gameplay. You pace around and find notes that are way too obscured by both the darkness and the dim object outline and experience a couple of jumpscares. I'd recommend updating the game where you do have objectives that are more involved than walking around, since lack of stuff to do is the biggest problem. Also the open door mechanic is a bit finnicky too, consider maybe switching to keypress/raycaster door opening.
Good luck! :)
