It is basically a game where you look at images back and forth and try to find the objects listed on the wall. The concept is simple, but it becomes surprisingly terrifying in practice. The tension is very strong, and it feels like a genuinely intense horror experience. I managed to beat it after about ten attempts, so it is not an easy game either. It is very fun, the words are randomly chosen, and it is a great horror game for the Scream Jam.
