Notice.
1. B can go down to the side from the stairs that slide up and down, but if that doesn't work, try going up and down several times.
2. B can carry R, but timing to move is difficult. Find the right moment when R doesn't try to get off. And when B is carrying R, be careful going up and down the stairs.

Technically it’s a 5* level but i removed a star as it not much fun carrying zbot the distance needed in this level.

The gameplay seems to be very dangerous, but you have timed the stairs and B bot's behavior very well to keep him safe. Well done.
This is a cool level. 5 from me!

Although the descent from the stairs hanging on the slider to the side is a trick in my opinion. I've seen it before (and I've used it in my level with tricks too), but it's very rarely used, so this trick doesn't have a name.

@Denis Nazin .. I would be interested to see your move. I used a routine SSS

It was quite interesting to see, that ZR is able to carry B without killing him... I didn't expect it...

@ridgerunner Thanks for nice rating.

Spoiler: VS

I even remember the demo level where I first saw this move:

@Denis Nazin... i had forgotten about that move. Thanks

@Denis Nazin Thanks for 5 rating! I used SSS when I was creating it, and tried to remove the need for tricks. But it's not easy to solve the problem. I understand that you're saying it's a trick. Maybe a kind of SSS..

@RonaldN Thank you. It's thrilling to cooperate with Z I thought, I'm glad you enjoyed it.

Although there are a couple of risky steps ,in overall liked the gameplay... thank you for sharing @Kojim

@delator77 Thank you! I'm glad you enjoyed it.

Yep, needed the VS to get started. Figured out the rest. Not as hazardous to B as I feared, although it was nervous play!
Enjoyed the level. Thanks

Once I figured out the direction of the first ball the test was very intuitive! Although it did get my heart rate up working with zbot. Fun challenge and thanks
