Knock-knock is an Indie Horror Game that was created by ice-pick lodge.
There is an unusual cabin deep in the woods. It had served as a laboratory and a dwelling for three generations of Lodgers. But as of late, the latest Lodger has noticed weird changes in familiar surroundings; items missing, strange noises and rattles heard. Something odd is coming out of the woods. Come night, it seems like someone's made himself at home in the twilight of rooms, attics, and cellars.
Stay awake and sane till dawn!
