Rings
At times, white rings will appear in the outer layers of the circles. Dash at the correct moment to collect them. The rings are a game currency used to purchase new color themes. Two rings are also awarded after completing missions. Because the colors are purely cosmetic, you can skip ignore rings if collecting them is too dangerous. In fact, some of the new color schemes make the game more difficult due to their distracting hues. You can also earn three rings by watching advertisement videos.
Scoring
Within each circle are small white dots. The number of dots corresponds to the amount of points awarded after you successfully dash inside the circle. If you hit the circle's wall however, the amount of dots will decrease by one.
Various General Tips
The regular walls will bounce you off if you hit the base of them. But keep in mind that if you catch the front of them as they are rotating, they will send you flying way off the side of the stage and kill you. You can collect coins which can allow you to purchase new circle characters. If needed you can watch a free ad video in order to earn three more coins. Quests will give you two coins apiece for completing them. To get the highest score possible, stop focusing on the coins and start focusing on simply getting to the next circle. Also, if you sit on one circle for too long you die automatically.
Walls
Two types of walls hinder your movements. There are spiked walls that can kill you when touched and white walls that will bounce you back. The white walls can still be dangerous, because you can end up bouncing off out of bounds. However when you bounce off a white wall the timer will reset. You can do this to gain more time.
