This is not easy at all to spot. 10 tries a few months ago, and only now that I came back I beat it in the first try. It might have to do with getting used to the new block appearance too!
I really enjoyed this level. I was lucky to understand the concept from the first, thanks to height of boards vs. amount of steps available: it was clear that some routes were not possible because too much consuming. So I focus on what was possible and it worked.
(10 years ago) Looks easy but it took me 20 tries.

EDIT 2022, 23rd Oct., - Again I needed to give it many tries (13). Adding stars to this Alkaline Phosphatase -u-,
