Blind Run is a co-op platform game with only 1 playable character. One player (playing with a joypad) can't see the screen, meanwhile the other one (playing with keyboard) can see it. None of the 2 can directly speak to each other using words. The keyboard player (Deaf Player) has at his own disposal a wide range of sounds, and needs to select five of those before starting the campaign. The joypad player (Blind Player) can only control the character, but without seeing what he's doing and must therefore follow the other player's instructions to understand what he has to do. The Deaf Player gives instruction using the game interface, and each instruction will be translated in a sound to be heard by the Blind Player. Using sounds during the gameplay, along sound panning and volume control, the two players must build together a language based on chosen sounds and improvisation to overcome levels.
