Click on the paratroopers to kill them. There are smaller ones that are worth two points. If you get to 50 points, you win. If the wall health is at zero, you lose.
Sometimes you're going to think you clicked on the paratrooper ,but you probably didn't. Might have to press green flag twice for everything to work. THE HEALTH DOESN'T ALWAYS WORK. I don't know why. But if the health doesn't work, then just restart.
