Hidden Stair!?

Wow! Really tricky but interesting level. It has an amazing although complex step to cross the building. Thanks!

What have i found so far: i can push B completely through a solid wall! I can get Zbot into the building. But as far as B goes-zilch. I was hoping that stopping B somewhere along the lower level would allow him to be squeezed onto the invisible part of the draggable but presumably the path lies elsewhere.

tap on the visible hole and move the "Hidden Stair"... wait a little bit to B climb the stair.

@chemi ..aaagh.. did this in past but must have touched the screen within the 15 seconds needed

Yes sir,yes sir!! Amazing level,very tricky but very clever...wow,that step was so cool and gave me a headache (croos the building) but it was worth!! Thanks again for sharing and excellent job @hadi

Sorry I forgot the rating!! Of course 5 shiny stars

@delator77 Thank you very much for your kindness. In the future, you will see good and interesting levels from me, which will be not disappointing.
Thank you again dear delator77

@hadi I love your levels...they make me think and when I complete each one is very pleasant my friend!! Keep it up !!
