Use the arrows to propel the green dot (you.) The blue lines and edges of the screen cause you to bounce away, but if you are persistent enough, you will be able to go through the thin blue lines surrounding the door. If the red dots touch you long enough, you will lose a life. The goal of the game is to get the key to the door and beat your lowest time. Sometimes you will drop the key and have to go back to it, which may cost you your life.
