Any hints on where B should tap? I was thinking Spoiler B should redirect R towards the step leading to white then perform the sticky trick(I had no idea what it is) then B can hopefully go onto R and low ceiling to the win?
Neat design on this little level. It's a one-trick level with a trick that is very unpredictable to assess regarding from what position to what position it works. All a player can do is use trial and error. Once figured out, it's not very reliable to execute. Maybe about 50% of the times it works. It's fun in some ways, but I'm not a fan of these tricks being used in meko levels. Spoiler: Solution Freeze R against the stairs. B is on the corner to sent R there. From that position, sent B to the tile to the left of R, and then to the stone block upwards of the stairs. B will magnatize against R and possibly mount R. Then you can tap the upper stairs for low ceiling and go to the win.
I love the disparity of opinions and perceptions that are given in this forum, always with respect... in my case, although I agree with @Block builder in relation to the percentage of success of the execution of the movement, this level seemed to me an example of another different and original way of putting B over R... once I realized what to do I got it on my third attempt, something that I don't find frustrating at all... thanks @Kureigeous68
