How many GB is Ontotis?

8 GB

That is more than the typical Indie game, which needs about 3 GB.

Leave at least 15 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Ontotis is a psychological horror game focusing on atmosphere, mystery and an engaging story. Uncover scattered clues to unveil the chilling fate of the house's residents, while encountering a mysterious humanlike figure seemingly connected to them in their haunting tale.
