You nailed the atmosphere, the feeling of isolation and I really want to see more. Excellent job using inspiration from Resident Evil 7, you pulled off some of the best darkness I've seen in an indie game ever.
A few minor bugs I noticed involving some occlusion culling, and I'd like to see the main enemy become more dynamic in their actions in the full game, but overall this is a solid 9.5/10 and I'll 100% be checking out the game at launch!
