Not sure where to start on this one. Tricks are expected so I used tricks and again found two shortcuts. I was attempting to do the level as intended but I still see no need for R? Spoiler: Shortcut1 Auto pilot onto the lift, do the Hercules push but only one block, do a ToA (Trip on Air) off the top onto the win mechanism. Spoiler: Shortcut2 Auto pilot onto the lift, tap the lower slider, auto pilot onto the stairs on the other side of the lift, walk over the zapper to the win. I know I used a few tricks and I don't know what you intended but you did intend tricks so I used them.
I won with B also and i wonder if that is a free draggable in the middle that has the potential to be lifted out to make R turn right and get on to the perimeter blocks then round to winblock.
I think that my way is the second shortcut by @gmacpro ... Spoiler: My way https://photos.app.goo.gl/PsY1SfWwhStSAGid6
