Indeed, this level is one of the harder ones. Let me clarify, There are three bones in the map, two on platforms and one on the left side of the map. All of them are left legs so u need to think about moving the bones in order, (Thats why u think u cant pick them up)
U can bump one of the bones with the button, and the other bone on the platform u can reach with enough speed so u can pick it up.
I suggest you try again, there are much more better levels awaiting after this one!
Thanks for the feedback, it seems that this level is slightly too complicated. 👌
