You can ignore anything that appears until you reach about 16 points. Then, tap the screen. This will give you a head start and save time.
Move circle to circle
Catch every circle that gets in your way.
Narrow circles
You cannot control when and the size of the circles created by your character. It can be difficult when your character only makes a very narrow circle and turns quickly. When this happens, release and immediately tap the screen. Unless you are at an extremity and collide with a wall, you will catch the same platform, but a with larger and slower circle.
Releasing
Release your character when it is on the correct trajectory. You will have more control when on larger circles.
