Blindfold is a first-person 3D game where the protagonist is a blind individual who awakens in a hospital and joins a program aimed at teaching blind people how to use sounds to navigate their surroundings. Throughout the program, the player encounters various tests and puzzles like escape rooms. After finishing each test the player is rewarded with an upgrade of their senses. The player can only see sources of sounds through particle effects that collide with the environment, as the game has no lighting whatsoever. By making sounds through actions like clapping or walking, the player can temporarily reveal their surroundings and interactable objects.
