@Andrea gerbillo - I wish you would give a trick list as I don't want to watch the video but I would peek at the tricks as I see a few but wonder if you intended that or not....
I really struggled with this level as I didn't see the way so thanks for the video. I needed it three times. I kept putting R beside where the 1st ball falls and R would get stuck for some time and then B wouldn't go either so I watched to video as I assumed that was the way but I was wrong.
My solution was not the same as that in the video, which explains that B’s final move was very tricky. Nice puzzle.
@Andrea gerbillo - Time to learn them. Here's a start for you Spoiler: Trick List In your video, you used Stairs Side Step Low Ceiling Auto Pilot Here's where: Spoiler: Video
@ridgerunner ok if i have understood correctly you have made a similar passage to this Spoiler: Alternative Final step
@Andrea gerbillo .. No nothing like that. You have used a type of momentum move and the resultant horizontal position of B allows a tap on a lower level. My move is a variety of Sideways Springboard Step. Here there is no need to tap behind a stationary B, instead as a moving B climbs a step the block to the side of the step,or any on the same level, can be tapped. Spoiler: Soft SSS
@ridgerunner thanks for the video I did not know that trick, or rather I have happened to use it without knowing what I was doing. it seems to me a nice alternative move for the final also because I tried several times but if I don't drop the high ball the move doesn't work so I still have to complete the whole level to get to the victory
