About This 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.

Gameplay Features:

  • Play time: 15–60 Minutes.

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

  • Warning: Uncomfortable audio.
