Just played this free game called Which. It's probably the most scared I've ever been playing a video game, but I'm kind of a bitch, so I don't know if it'll creep you guys out as much. DEFINITELY play this with the lights off and with headphones.

Only takes a few minutes to play through once, and there are two endings depending on what you do in the third room.
