Finally

Spoiler: L might not needed

You might not use L in your gameplay. L is just there to stabilise/support the last ball roll. If you tap quick enough(before the ball rolls off B has dismounted), then L can be ignored. But just in case, I added L in for a safer/cleaner/no timing needed gameplay.

I think i probably have the correct gameplay but not sure i can face a restart. The biggest problem is waiting 5 minutes for P to push the budgeable(have endured this three times), then several minutes more waiting for P to walk in a straight line from the metal step to the stone step. And the last high ball has not falled in a straight line but has veered to the right twice, denying B the win.

@mastersifu - I'm having a challenging time with the timing, but I may be doing something wrong. After P drops the first ball I have P step onto B, then herd P to the lower level. In order to avoid P getting stuck at the fence I think I need to freeze P on the middle slider then have B run around P to block the path. Is that correct? I've successfully done that a few times, but have had a hard time repeating it, because I don't get to the freeze fast enough after tapping where B needs to go.

Gave this a fourth attempt but after one lap PillarR refuses to go any further.

Spoiler: Video. Reveals my gameplay

Changed my gameplay at the end to avoid the step problem and had to prevent the two pillarbots bumping each other but got the win. Very nice gameplay in theory but too many problems in practice.

@ridgerunner - I had a similar issue but on the other side. PR would go down and not go up the metal stairs so I couldn't drop the last ball. Looking at your game play, the last ball wasn't dropped yet??? I wasn't seeing the ending anyway and gave up.

EDIT - Now I see the ending - thanks

@MekaSage I would say that you are right but there is a less timing-dependent way. After you have P down, freeze P in front of the fixed draggable, not on the fixed draggable. This allows B to go to the lift and then let B stand on the fixed draggable so that R turn to the lift. I can see your method but it was too risky and the timing was too tight.

@ridgerunner .
I agree that P takes a very long time to push the budgeable but in my opinion, I will not categorize it as a problem in this level because nothing was wrong with this move. It is just slow.

The metal step and stone step issue wasn't a problem during development so I figured it should be ok. But it is sad to hear that it annoys you. Do you know why P refuses to walk ahead?

Thanks for playing, commenting and rating. Sorry for the problems which took you five attempts to get the win.

@mastersifu ..thanks for the reply. I have no idea why the steps caused a problem. I ensured the budgeable was fully pushed in. PillarR always managed to do one lap so for my win i rushed B to get PR down then herded PL at the same time. The top ball fell cleanly when i used the correct bot.

Wow!! very clever & challenging logic level... glad to be able to solve it... thanks for sharing @mastersifu

@delator77 Did you face any instabilities when playing? I'm glad to see you managed to complete it too. Thanks for playing, commenting and rating.

@mastersifu No!! all worked well... the only "issue" was the time P spent pushing the block ... between 2 and 3 minutes

@delator77 You must be saying 'Finally' when P done pushing the block.

@mastersifu jajajaja,yessss,now everything makes sense
