Not Alone In The Dark

This was created during the 48 Hour Global Game Jam 2013.

You begin on the 2nd floor of an old mansion... the lights have gone out.. you hear a sound.. you are NOT ALONE

Your heartbeat pulses and at that moment you get a flicker of your surroundings.. when you're scared your heart beats faster.. and the flickers increase till you are no longer in danger and can calm down..
