Absolutely fantastic. I think what you're doing with the overarching theme of the game is great. It doesn't rely on jumpscares and the immense tension that builds up over such a short time is just fantastic. The atmosphere is immaculate, especially being someone who came from a region where coal mining was king. My only slight critique is that the log puzzle near the start was kind of annoying. Really hope you continue this project into a full game some time!
