Get Higher

Excellent challenge, yes sir !! But I have completed in a very different way ... as @Block builder we only agreed at the last minute but unlike him I have not used the head of any bot to be able to do it ... even then the challenge was so difficult that I feel satisfied because I have simply done it in another way but without resorting to any shortcut .... reading @chemi 's spoiler I believe that I've done in a similar way!!! Anyway....WOW Spectacular level ... thank you very much @gmacpro

Re-reading the @Block builder spoiler I have realized that I have misunderstood and that he has not used the head of any bot .... sorry !!

@delator77 - Thanks for playing and commenting. If I would have placed a stone pillar in front of the top ball, then the other ways would have been limited. Lesson learnt for future levels.
