Here’s another starter game. The object is to catch the positive balls and let the negative balls fall off the screen. If you catch a negative ball or a positive ball falls off the screen, your score goes down. Your score goes up when you catch a positive ball. The screen is green as long as you score matches the current high score. The screen turns red when you start to lose points. You win when you reach a score of 1000 or more. The game starts with a ball dropping every 3 seconds. As your score goes up, the balls will drop at a faster rate. A ball every 1/2 second is the fastest. To move the bucket, just slide your finger anywhere left or right. This is for anyone who wants to add to it or just see how things are done.
