This game is absolutely terrifying, it's simple premise of a reverse prop hunt can make it seem like it'd get old soon, but it doesn't. It maintains a constant horror by not only making simple props attack you, but eventually other entirely un-hidden monsters. Its controls are tight and responsive, and while the game is quite difficult, it manages to be fair at the same time, even the most obnoxious enemies I've encountered so far felt fair. (I hadn't accounted for their speed.) The game is only $13 and more than worth it, even the free demo is worth your time and worth replaying.
