Are any tricks used?

@Link I think I've reached the endgame (all balls bumped, two stars collected) without any tricks at all. But I'm now out of ideas. Everything I've tried has failed.
@cimarronline Me too.

Spoiler

The nearby overhead rail thwarts all attempts, and B on P won't work either, because of the horizontal stone pillar. I'm not entirely sure of the role of Z here: he can be herded so that B can avoid him, so maybe B has to die for the win.

Given that this is a @Fendi level, there's probably something unexpected waiting for us. (I would never have predicted the ending of Slips Trips - it happened all by itself. ) Perhaps there's a clue in the title.

I'm glad I'm not alone in my head-scratching.

Spoiler: Video Solution

Could not get L to the finish when I looked at this yesterday but decided to exhaust every herding option this morning and finally got L over there. I much prefer the move to get R away from the step gets isolated on. I discovered this with L first time.

Thanks, @Fendi, for the video. The solution's not as elegant as I'd expected, but at least I now know it's possible.

Spoiler

I had already tried the key move (which happens around 05:50), but without involving R, just B.

I won't rate, since I didn't solve the level unaided.

Wow!! brilliant tricky level,very complex so I am very happy to solve it by myself ... thanks for sharing & for the fun @Fendi

Spoiler

At 5:50 I've tried, it doesn't work, then how about when L (P) spin around and get stuck in the wedges? Of course it needs R's help, and that is easier certainly with R's help. Can you make the video when L (P) can make it through the wedges and the pillars without R's help?

The first part with all the balls was no problem....but then OMGOSH it got tricky. Needed help from the VS so thanks for including it. Awesome intriguing level

@Sammy 5
But I feel like maybe this level is too comlplex, sometimes only a few player can figure it out

@Fendi yes it is complex but including a video solution helps people to learn and grow their repertoire of skills and tricks

Amen & yes to VS. I'd be useless w/out most of them & this is one of those. I'm not too proud to admit when I'm dull witted & drawing a blank.
This is clever, I'm not.

Oops, see, duh...
