Contrast

Wow,excellent and very clever logic/tricky level!! When I completed it,I had a strange feeling that I did something wrong(I used a "strange" springboard stairs to access with B where he "couldn't" go)...Then I saw your movie and...!! Thanks for sharing and excellent job @Star Penguin

...

if i may ask, whats the function of R which stand diagonally?

edit;
now i know
its for blocking B from zapper

Sadly, this level has succumbed to 'improvements', and it appears unsolvable in v1.3.1.

Spoiler: Why?

Namely, R in the metal half can't cross from the ball to the wedge.

Is there a 'trick' which will overcome this problem (other than a tweak to the design)?

@cimarronline Thanks. I hadn't realised that the wedge wasn't the only problem. Version compatibility is becoming a minefield.
I have v1.2.7 on my phone and I run v1.3.1 on an emulator. I wish there were a (simple) way of installing more than one version on either of these devices, so that I could solve any level on the version for which it was designed. (Sometimes I even wish I hadn't installed v1.2.7.)

@cimarronline Thanks very much for trying, but the new version doesn't work for me on v1.3.1. After a few seconds of contorting on the rotating ball, R turns upside down and falls off. It's a shame, but R's instability was after all a bug, and it has finally been fixed.

Many similar obsolete levels will have been created in the 4 (?) years without updates. So please don't spend any more time on this for my sake.
