The gun in the Amazing Cannon game will shoot colorful balls, but this is not important for completing the tasks set at the levels, but the fact that you must fill a special container, which is located at a distance from the gun. If you start shooting, the balls are unlikely to hit the target, so you need to use the various devices that are currently on the field to redistribute the direction of the balls. The supply of shells exceeds the need for filling, but this is done intentionally, in case some of them fly past. But in order to complete the level, you must reset the value that is on the container in the Amazing Cannon.
