changes: removed an R shortcut on the roof, changed only a single piece, using the R lock column trick learned afterwards.

Spoiler: Hint

to solve, you must use ALL the sliders and stairs, even these hidden ;-) and go up, or down, and sideways, when needed. Beware the few frying spots, move carefully. Some point require precise view angle to move (enable free view angle!). Finally, push the R away and reach the win spot on the roof.

Spoiler: Beginning steps

you go on the right corner, passing by hole by lowering the first elevator (hidden). Then by the little corner stair, you could climb on it. Move the two right side elevators both up, to first level, move B on the second one, and use that to bring B down, to the long stair begin on long back side. Climb up that stair and...

From my perspective, this is just a nice puzzle. Not very difficult.

@GFJ Thanks!
Yes this is my first level out. I think it is middle difficulty, but may be wrong, I could change my difficulty rating if necessary.

Excellent first level!! Not difficult but I like the path and the gameplay is fun...Pleasant design too...Thanks for sharing @Alberto

Nice puzzle thank you. I enjoyed the journey, but it was often difficult to get hold of the sliders or tap in the right place due to things being in the way.

@Jom Yes, that is wanted , there's some point (say when turning around the elevator on top of stair) were you can only continue by finding a special point of view and zoom level, to be able to tap there.
And of course, you need free view angle!
Thanks for rating
