Ball Blaster is a new arcade game related to numbers. It is also a very interesting shooting game. In the game, some digital squares will drop continuously at the top of the screen. Your task is to control the cannon to avoid these blocks while firing the cannon upwards. The number on the square is the number of times you need to shoot. Only by accurately hitting the square can the number decrease. You can increase your strength, increase your firing speed, and even change the color of the cannon.
