Impossible parkour

Hi can someone fix the lillypads at spacejunk?

I too have had a problem with the parkour. In the golden course I got to stage 29, after many attempts I finally completed it. Then I jumped down the crater and ended up at the sign that says stage 30. So I ran through the door, but in my excitement I fell by accident off the platform and straight into the lava. And to make matters worse the game sent me back to stage 29, was there no checkpoint at the place where you clearly entered stage 30, or am I missing something?
