Collect rings to build up your chain. The long white bar that appears at the top when you collect a ring shows how long your chain will last. The upper left corner shows your high score. The upper right corner shows how many rings you need to get your next boost and how many boosts you have. The number in the upper middle shows what your current chain is. The safe zones stop your chain timer from going down. There's no health limit, but if you get hurt your chain ends.
