Oof, yeah the heart was pounding with this one. Great sense of unease walking through the looping rooms, really set me edge just dreading what was going to be behind one of the doors. I enjoyed piecing together the story through small breadcrumbs, and it, along with some other obvious things, reminded me of PT. The camera focal length was quite high for a game -- it worked well to add unease during the intense parts but might have been a bit cumbersome for the normal navigation.
