Nothing To Hide

@richardfu_ I've tried such things initially, but deemed it too difficult.

@cpw has the intended solution. @chemi there is no killing involved in this level. I love B, I wouldn't approve it. But, that solution by @richardfu_ is like... What?!!!

I used most of CPW method but

Spoiler

[i used falling trick to get B to floor and at the end i found R would fall off zapper bot unless the slider directly below winblock was slid across]

That was my major "I think that's a red herring".

Until about 3s before I solved the level.

So we considered adding hints yesterday, and today there are multiple solutions?
Unbelievable solution @richardfu_... I'm speechless...

Unbelievable level,so complicate to me!!I must accept that without the help of CHEMI and CHUCKTULHU(my spanish meko addicts friends jejeje)I would never pass thid level....AMAZING

Awesome! But very very very difficult, without the spoilers could not do it.

@delator77 and @Jose Luis Galiano I'm glad you solved it! Don't you think it's funny how after you know the solution, the steps to reproduce it aren't really that complicated?
Now if you want a real challenge, try @richardfu_'s solution...

Nice Puzzle!

Thanks @TR O!
