I can not beat level 47.. Can not climb the jump thru platform after the 2 hills.
Thanks for playing, wow you're very close to finishing it.
If you are referring to the sand platform at the far right of the level, the trick is to only use it when getting back. Try to jump way over it so you don't touch it, then, step on it when getting back to the left-side of the level.
I hope it helps, I'll post a complete walk-through video soon. The last levels are the most difficult, but once you understand how it works, you can defeat them easily.
