I love the graphics and you did a fantastic job with the ambiance and the lighting. The game constantly feels unsettling because you know there is something somewhere but you don't see it.
However, as others pointed out, it's a bit buggy and cannot be finished. When I picked up what turned out to be the password, the subtitles only said "It seems stuck" because I interacted with the computer next to it at the same time. When I turned on the generator, the lights did not turn on and the HUD disappeared. When I got into the elevator, I could walk and throw flares but the screen just stayed dark.
I'd love to revisit the game if you fix these issues, it's been almost a month already.
