Knock Knock!

Knock Knock! is a horror game set in a pitch-black mansion, where you navigate by listening rather than looking. Follow a steady, rhythmic knocking to find a door and answer it.

Navigate by sound

Your footsteps reveal different floor materials and help you work out where you are. Haunting sounds create “Soundmarks”—audio landmarks you can use to build a mental map of the mansion. Binaural spatial audio creates a 3D soundscape, with cues muffled through walls or dampened according to their direction relative to your ears.

Accessible play

The game is designed to be played with zero visibility, offering a nearly identical experience for sighted and visually impaired players. Menus and text are read aloud automatically, without requiring an external screen reader. A playthrough takes 15–60 minutes.
