Press the green flag to start the game. Use the right and left arrow keys to move the donut to catch the jar. (You can see your score in the top left corner of your screen.) Don't let the jar touch the ground, because if that happens 3 times, then it's game over. If your score gets up to 20, then you win. Press the space key to stop the game.
I learned how to make a bounce game from a Scratch tutorial.
