The problem that you'll run into is evident immediately - while there may not be security guards or cameras, there are ghosts. The kind of ghosts that kill.
The idea is to explore every corner of the building collecting bags of money while being careful not to run into any paranormal presences. If you notice the furniture start to shake, or you start hearing strange sounds, it's time to run away or else face a horrible creature, and near certain death.
You will see eyes drawn on the walls of certain rooms. Touching these drawings will reveal frightening images of different locations within the building.
Eyes: The Horror Game is a good horror game that brings a new experience with each playthrough, owing to the fact that everything - the location of the bags of money, the distribution of the eyes, and when and where the ghosts appear - is set at random.
