Just wanted to drop some praise to the dev team; this was terrifically well done. Most "PT-likes" in this vein fall flat as they are just uninspired carbon copies, but the escalating tension coupled with fantastic use of lighting and audio really made this stand out. I was peering round corners and behind my back with each new corridor just waiting for the inevitable, haha. First time round I did encounter a bug in which I fell through the floor and out of map though, and sometimes the lighting on the television set would appear incorrectly in certain loops when turning the telly on with the remote. A few niggles aside though this was really neat, nice job to all involved.
EDIT; Watching Queen Faith's vid, it seems they also encountered the bug with falling out of map toward the end.
