When you click play, the green box will move down the screen. When the Filled green box is on the right side, click the right arrow key. When the Filled green box is on the left side, click the left arrow key. You will keep earning points until the box reaches the bottom of the screen, when the project will stop, and you can play again. The high score is posted on the leftmost side of the screen. Have Fun!
