To control your character tap on the right side of the screen to get him to go to the right, and tap on the left side of the screen in order to get him to move left. Be sure to watch out for birds that get faster and faster and bigger and bigger as you go for higher and higher dives. As you fall during your dives you can collect diamonds. Save them up to purchase new characters. You can watch free advertisement videos in exchange for 100 free diamonds.
