Unicycle challenge

Today we will transfer you to a world of clever people who can do a lot of things. They can jump over one leg stretched a rope over an abyss, and do many other things to the extreme. But today you will be a little safer to execute things. You will need to keep a balance on one wheel, which is fastened to the usual chair. Try to survive as long as possible. Sometimes, when you will be hard, you will need to try to jump, then everything will turn out exactly!
