Creepy Hide and Seek

Each player in the game of hide and seek plays the game alone in their homes or apartments, but they can communicate with each other via computer and text messaging. Each one of the players must perform a ritual to summon a ghost, and then they must hide from it to experience the thrill of being tracked by a spirit. If the ritual is not performed in a very precise manner, the person is murdered when the ghost finds them. (Summary by p00q)
