At this level I applied the movement of P by turning between the stairs and taking B along. I tested this movement several times and there were no problems. No tricks are needed. Only control of the behavior of P.
... excelente mr. @Jóh Spoiler: solution enjoy the song (about the video, I record with xRecorder app and to input song I use inshot, when u finish edit in inshot, just choose highest resolution, because when u upload in youtube, our video resolution will get worsen)
@Jóh - I'll not rate as I don't want to encourage hidden. I seen your move right off and it worked. The level had a terrible instability, the ball that P needs to walk over didn't rest and P didn't like that at all. Moving the lift beside the ball caused the ball to move and I can see a newbie falling for that... P walked diagonally after that but I still got to the win.
