Remix challenge: Reverse the order and hide the sprites. Add 3 more broadcasts to the code. Each broadcast hides a single sprite until there are no sprites shown. Remix Challenge: Add three backgrounds. Start with sprite3 counting down (3,2,1) then send broadcast4. Have Sprite2 count down (3,2,1), hide, and send Broadcast5. Sprite1 counts down (3,2,1) before it hides.
