A second, and slightly more complex way, of making your game more challenging would be to incorporate another moving ball into the mix. Let's do that here.
To prepare for this, import another ball sprite, perhaps the basketball or baseball. Give this new ball the same script that you gave to the first ball. Also name this ball Ball2 instead of Sprite1.
Both balls will now bounce around the screen, but will seemingly do nothing special when they touch. Now the challenge becomes to make these balls bounce off of each other.
To accomplish this task, start with either sprite's script area. Ultimately, we'll add the same script to the other sprite too.
