About Knock Knock!

Knock Knock! - about the game

Knock Knock! is an experimental horror game played with your ears, not your eyes.

You are trapped in a pitch-black mansion with zero visibility. Your only guide is a constant, rhythmic knocking. Your objective is simple: navigate the darkness, find the door, and answer it.

Your footsteps distinguish various floor materials, helping you understand your location. Haunting sounds around you create "Soundmarks" - landmarks made of sound - to help you mentally map out the mansion. You must use these cues to finally find the door and see who is so determined to speak to you.

Binaural Spatial Audio:

The game utilizes Binaural Spatial Audio to replicate 3D soundscapes. Cues are muffled through walls or dampened based on their orientation to your ears, providing a true sense of presence in the dark. Your footsteps distinguish various floor materials helping you orient yourself.

Visually-impaired Accessibility:

Designed from the ground up to be played with zero visibility, Knock Knock! provides a nearly identical, high-tension experience for both sighted and visually impaired players.

Gameplay Features:
  • Play time: 15–60 Minutes.

  • Zero visibility Exploration: You must navigate the mansion with zero visibility, relying solely on your ears.

  • Soundmarks: Use haunting audio cues to mentally map the layout of the game.

  • Native Narration: All menus and texts are read aloud automatically, requiring no external screen reader setup.

  • Warning: Uncomfortable audio.

*Headphones are recommended for the intended binaural experience.
