Use Right arrow to move right and Up arrow to jump. Avoid the black lines, if you hit one you will go back to the start page. Tip: try getting the black lines in between your legs. It's way easier that way.
Getting over black lines is very tough, you need to put a lot of energy in pressing the right arrow while you are up in the air. I made sure everything was possible though. If you find any glitches please tell me! :)
