the labyrinth game is a game that only uses sound to find your way.
you are a bike-courier and have to make a delivery. you ride a real bike (like a hometrainer) and by the luminosity of your front light, the computer detects if you are riding, stopping or turning.
then the sounds you hear change. that way you can hear where you are.
