Catch the diamond!
You are a small ball. A cute yellow one that is. Your life long task is to collect as many diamonds as it is possible. With the help of a trampoline, you finally can into the skies. Off you go, jump!
The colored areas in the third screenshot mark the areas where you can manipulate the movements of the ball. If you move your finger on the blue area, on the left side of the screen that is, the ball will lean to the left. The red area is like the blue one, but if you move your finger on the right side of the screen, the ball will lean to the right.
