I like the idea, but is this a shortcut? Spoiler The star above the fence can be taken by another slider.
@Block builder It seems like it is a real shortcut … Some false - and very little - shortcuts can be realized if we let B walk a little (to bypass some small action or to correct an error in the order of the sliders) … but for my final and winning try, I was happy to perform as intended : with a completely non walking B. Thanks to the author !
Nice work. I had to restart when realising some sliders had to be moved first before B could go in the right direction.
