I like the aesthetics of this game, it kind of reminds me of Slender. I agree with the other comments about optimization, though, it definitely chugged a bit on my 3070. The audio design was also really strong!
I *think* the ending was bugged for me; I collected the key from the skinless man but I was unable to go through the main gate to continue. I ended up watching someone elses stream to see how the demo ended. It also seems like a lot of props and even a few buildings don't have collision... You can just walk through the building right behind the skinless man.
I played it here on stream around 36:00
