Three Chaps

Spoiler: R/L Behaviour

- offset block (if R or L walk onto a block that isn't centered then R or L will become unstable and may jump off)

Spoiler: Video Solution

I suppose my gameplay was similar but for the first two thirds of the level i used different bots for everything. Maybe I should have realised that when the low budgeable zapper didn’t fall at the first attempt. However I enjoyed working everything out and my last third after the lower ball was pushed was the same.

Spoiler: What i used

Pillar for the first ball and R for the low zap budgeable and R on Pillar for the high one

...
gameplay at beginning is
suprisingly fairly easy.

the set up at the end,
where there is halfway dragable block,
I directly realized, should be used
for stumbling. and you use R's eye,
to work similiarly like ball,
to make L bot stumbled.

very cool.

Very nice level but like @ridgerunner I used differents bots in the beginning so the gameplay changed until the end, that was the same...

Spoiler

highest ball pushed by L,the zapper budgeable pushed by R & the highest zapper pushed by L onto B

your solution is more sophisticated than mine which seems simpler ... thanks for sharing & for the fun @Meko Guy
