Moving Stones

@Serge Hi! is pure logic or any trick is needed?

Well, as I did not see one element I was a bit lost (that was the reason of my doubt) but after found it I completed the level relatively easy... in fact the last step was the most difficult one ... but I did not use one thing & I am curious about what is its purpose... look at this...

what is its function?
in overall a fun level with nice design, thank you for sharing @Serge

I searched far & wide for all the far flung bits, but it all comes together for B's path. I agree with @delator77 on the unused auto slider & the last move.
Got it down, tho, & got B to the win. I liked the recovery point, since the last move took many retries. Good job!

Hi
This is the first step of the level, used to move the first object placed in the water. But if you have seen the drag element on it you don't need that
Thanks for your comment

@Serge ahh, I see it... as is a FD (Free Draggable) I moved it with my finger

@delator77
I hoped that somes guys don't see the FD but I loosed

Really liked finding all the sliders, but not a big fan of the chance throw at the end. The level seemed so sophisticated up until that point. Very creative and lovely center structure. Thank you
