Ride the track on roller skates. There are many obstacles ahead. Therefore, you will have to master the aerobatics of driving. To go around the barrier, you need to either connect your legs, or try, literally, to sit in a transverse twine. Be careful! The speed picks up very quickly. And that means it will be easy for you to make a mistake. But don't despair if something goes wrong. No one is immune from mistakes. So a new chance. New try. And forward, towards victory. Remember that he who does not fall does not rise. Good luck in the game!
