Shoot down the balloons, soldier! Click and drag to aim the catapult, and wait until the crosshairs appears, and then release the left mouse button when it is on the balloon you want to shoot down. Every time a balloon passes the black line on the top of the screen, your health bar will decrease. At the end of each level, if you are still alive you will be able to spend coins you have earned on upgrading your catapult. You will also earn several different weapons throughout the game. Click to choose your weapon. Some weapons have a limit, and a reload time.
