Knock-Knock: A Unique Horror Game With an Environment-Based Fear Factor

Knock-Knock is a survival horror game developed for Windows by Ice-Pick Lodge on Unity. Unlike most horror games, the fear factor in Knock-Knock is achieved by using the environment. The game’s plot is full of unclear moments and allows for multiple interpretations. The main objective of the game is to help the Resident survive in his house until dawn. This can be achieved by walking around the house and turning on the light in its rooms.

The gameplay is affected by the Resident’s bad memory and eyesight. Lighting is an indicator for the appearance of enemies as it turns off when someone is close to the player. The game also features a relative time system that can pause, pass as usual, or go back, depending on the player’s actions.
