About Ontotis
Ontotis is a psychological horror game about Robert, a man grieving the recent loss of his wife. Seeking peace and solitude, he takes a remote job caring for abandoned properties, but a final assignment on a desolate hill turns into a night of terror.
Story
As a severe storm cuts off the outside world, you must secure the property. Routine chores give way to unexplained phenomena in the halls and the appearance of a mysterious, human-like figure connected to the house. You investigate the property, uncover the tragic history of its former residents and confront the presence lurking there.
Investigate the house
You solve puzzles to advance the story and unlock secrets. Scattered items and pages provide clues to the mystery, and the items you use and mysteries you unravel affect which ending you reach.
