The first quarter of this was good. It captures the fear of isolation while walking through all those halls (as well as trigger the claustrophobia in you while crawling under tight spaces). But after that, the rest felt mediocre. It pretty much became a walking simulator, since there's really no threat that came at you. Nothing shows up to ever chase you. Just lone pieces of furniture placed on separate rooms and that's it. The only exciting part was the last scene, when you're ejected off the premises, lol.
