Use the arrow keys to move left and right. Every time you touch the shield, your score increases by six. If you touch a meatball, you become a meatball and you lose. If the green on the bottom doesn't appear, press the flag again. Or you can just double click on the flag. That also works.
This game is a sequel to my first game on Scratch, Meatball Apocalypse. This was actually the original idea nut at that time I couldn't do it so I switched it to something easier. Now I can finally do this.
