Cappadocia

This is one of my stort level which has the same tricks as Bots & Co (My latest level) with some zappers. There's also a shortcut if you wish to skip R part:

Spoiler: Shortcut

There is a stair in 2nd room, make sure to stop B right there and wait for R

I had to chime in for the opening move. I can see three ways to start and none are very stable.

Spoiler

1. B can push the low ball to the left and then auto pilot over the stairs with momentum to the other side - not stable - either it works quickly or not at all even after 20 tries. This would be a shortcut as the upper ball isn't needed.
2. B can ToA at the top of the stairs, on the half pillar and fall but also not easy and
3. B can hit the high ball, get out of the way, HOPE that one ball falls towards B and auto pilots up and over. I believe this is the intended way but I was only able to do it once and I tried many times.

I did win no thanks to the hidden zappers and it was a nice design and mainly logic - so thanks.

@gmacpro Well... There are many kind of opening... The third one you said is almost my correctly gameplay. Well... The ball will push the low ball in some way to the left (or right and the high ball falls to the left) so you need to climb the pushed ball to the left and get to another phase easily (or not?)
Thanks for playing!

@Tadashi Suzuki - Well then as I said, your intended way isn't too stable as I was only able to get it once and on that attempt, it was a miss tap by me. Normally, the rollover ball would fall to the opposite of B but the other ball would stick on the pillar....

@Tadashi Suzuki a question...all the balls are needed?

I think i must have won by a shortcut by by the sound of things. Won with B. Liked blasting that ball. Delicate touch was no use.

@delator77 ... Mostly

Wow! Excellent logic level!

Wow. Red herrings, secret passages hidden in plain sight, and things needing bypasses... This one had me stumped for some time. But once solved, it really wasn't that hard. Thanks for pushing me!

Oh, and fwiw, I found the solution to be very stable.

Challenging level ...Thanksfor sharing @Tadashi Suzuki
