Ok, this one nailed the horror atmosphere outside. I knew he's coming, still jumped. Played 3 times, couldn't bring the second one. Won't try again as I'm not a fan of jump scares. The rooms are quite big, if you'd make them a bit smaller it might make the space a lot more comfortable to explore and make it easier for you to design the interiors. I like the UV reveal idea. Also either the trees or the player have too big of a collider. It was annoying to not be able to go through 2 trees when it was obviously a big enough gap.
Well done on your first real game! Has the potential of ruining someone's pants!
