"Circle Shooter" Game

Circle Shooter is a game where you are given a spinning cannon. It doesn't stop spinning until the end, so you have to be very careful with it. White tennis balls will be flying at you. Your task is to prevent them from hitting you. And to prevent them from hitting you, you need to hit them. Seize the moment when the cannon is turned on the white ball and shoot. After that, the ball should disappear. If not, you need to make another shot to finish it off. Be very careful, because the cannon is in rotation, and you can't always hit the target you would like to.
