A Dark Room starts with a few lines of text on a black screen: “the fire is dead. the room is cold. awake. head throbbing. vision blurry.” A bright-blue line cuts across the center of the screen, just below the words “stoke fire.” You press the words and suddenly the screen turns white. More text arrives: a ragged stranger has stumbled through the door. You keep stoking the fire, the thin blue bar disappearing and then slowly filling itself out again each time to signal when you’ll be able to press the “stoke fire” button again.
