Take your time

Great symmetrical design & FUN gameplay...maybe a bit...

Spoiler

Hidden,I mean,the draggable to release R...As I am quite good with timing levels I tried to win with one tap but hey sir ,you have adjusted the timing perfectly ... with 0.1 extra time I would have achieved it

...Thanks for sharing @Mark69

...
another masterpiece from you

@delator77 Thank you, effectively I tested very accurately the timing, also taking in count the occurrence wherewith B could fall and/or roll onto the target, occurrence I avoided designing the target higher than platform.

I have what seems to be an alternate solution.

I was able to swing Z from the lower platform around to the back, elevate him to the platform, and with a suicide-B herd him to a walk up the stairs to a win.

I'm stuck huhuhu

I've already directed B to the highest stair block and I'm not sure what will happen next.

I won with Z. I tried @wbogacz 's method.

@wbogacz Well, that’s not the original intended (that I work hard to realize trough a very articulate mechanism), but, anyway, it’s a way to win... ​

@P_simorf Would you like to found also the original intended solution? Obviously, you need a R to win...

I mean, sacrifice B is never a nice solution for him...

@Mark69

I already placed B to the upper stair block and I'm quite waiting for something to happen. Maybe I'm too impatient to wait.

@P_simorf I didn’t say you have to place B on top of the stairs, but I said that you need a R to make something and win (in the intended way, sure)...
