In Ball Blast, you must protect the surface of the planet from the cubes falling on it. Each item will show a number that indicates the number of hits needed to destroy the item. On the surface will be visible wheelbarrow on wheels. It will be installed gun. Using the control keys, you will have to move the cart to the right or left and place it under the cubes. As soon as you do this, click on the screen and the gun will begin to shoot at the cubes with special shells. If you hit them, you will see how the numbers will start to reset to zero, and in the end the object will collapse and you will be given points.
