This is a beautiful but deeply unsettling demo.
Seeing everything get revealed with the scanner is extremely satisfying and the different colour palettes in each level creates a gorgeous aesthetic; I feel like I could spend hours just pointing that scanner all over the place and getting every last detail. But at the same time I was very uncomfortable with how some shapes appeared and while the beating heart sound that accompanied the scannable objects did get me tense, somehow it was the objects that weren't marked which made me more nervous. The idea that something like a deer and an outhouse gets marked but not a graveyard just gave me a bad feeling and added to the atmosphere. Also I don't trust Scanny. I don't know if it's because he doesn't seem entirely certain of things himself or just because he reminds me of Clippy but I don't trust him. Overall I loved this demo, I will definitely be keeping an eye out for the full release as I'm very excited to see the other levels.
Final note is that I was not expecting to get jumpscared by a goose.
