Whenever it gets loud, the traffic light stars to turn on. Once it gets louder than the red light, it inputs the times into the "Times" list. First click the green flag. Once the game is on, press "Space". It will start the timer. You don't need to play with the timer, but it is fun to look at your scores. If you click "D", it will delete one time from the Times list. MAKE SURE TO DELETE YOUR TIMES BEFORE YOU LEAVE. Have fun!
