SImple action game for Commodore 64. You take a role of a priest, trying to survive in a haunted house by performing rituals to stop haunting. The game is unfinished and buggy. Move priest around with joystick. Whenever there's haunting around you, find a spot where your character turns black, and hold down mouse button. Then push the directions indicated by the God on your cross to perform a ritual to get rid of haunting.
