@hadi Spoiler 1) I knew B with a trick could climb on a cube, so I tried to build a cubic staircase and it worked! 2) Sometimes you have to wait for B to push twice before lowering the wall and jumping in the other area.
@gmacpro This time it was the only move possible. It was imaginable that the ladder would move. .. Anyway I promise that next time there will not be anything hidden. Find all passages in the spoilers
Another funny level!! Really enjoyable....the last jump I did it a bit different... Spoiler I was able to do it with springboard stairs but your "jump" is cooler jajajaja Thanks for sharing and well done @stefanovime
