Leaning for You

Spoiler: Video Solution

That was a very nice move at 2:10 .Bit annoyed that i didn’t see it as i had B horizontal in that area but failed to see the potential . My gameplay was the same up to that point.

Spoiler: My gameplay

I used the tendency of B to ghost on metal stairs, to push L on PillarB onto the stone half dome so pillar moves onto the lowered ball and pillar walks to dislodge L using the overhead fence.

Very nice tricky moves ... thanks @Meko Guy

Good one. I found it on the easy side for your levels (i.e. still not easy at all). Did most the same as in the video although in a different order. One part I did differently.

Didn't do the autopilot to make B horizontal. I sent L on to the big horizontal slider, and the slid him on to the fence. After that B can be positioned normally in the remaining gap.
