Use a powerful cannon to break the rocks containing the numbers in Ball Blast. Shoot the rocks and avoid their impact on your fortress. Score for the longest time possible.
A flurry of rocks fall on your side and you have a powerful cannon so you can shoot them before they hit you. These rocks are not normal because one shot does not mean they have completely disappeared and they fly in all directions until you completely shoot them all.
The rocks have numbers, once you shoot, this rock will split into smaller rocks and fly around the screen. Their rush when you can't shoot all from the old rock, the new rock has appeared. You slowly shoot them all so that there are no crumbs or small rocks left. At the same time, stay away from the onslaught of rocks that are trying to destroy your fortress. The game will end if your fortress accidentally touches any rock. Score the highest score and keep the match as long as you can get through.
Use the mouse to move your fortress and shoot and avoid the obstacles of the rocks.
