Can you hear me?

Can you hear me? is a game where get only one of your senses: hearing. You are in a place and there's another person speaking to you. Find that person.
The game is just a black screen. Use arrow keys to move around. You hear footsteps when you are moving so that when you don't you know you've hit a wall. TO CLARIFY: When the game starts there is no sound or visuals. Just start walking with arrow keys and you should hear something.
The game is best played with headphones on or with surround speakers.
