@B Hill and @GtB - I initially finished this level the same way as you. @Rohan Kumar My sincere apologies. My hint to you was based on the more difficult solution. Spoiler: What my hint implied What I was implying with my hint to you was that: just like when B had to make himself a path with the other balls, the same was true here: get the final ball on the lift and then B onto the ball and ride it to the win. In the end, that was not the intended solution. Also, when you mentioned a "lift" in your first comment, I initially thought that that may be a hint to some players. After more consideration, I believe that the lift was not meant to be hidden and thus could be freely discussed. Again, my apologies. @vince Spoiler: Suggestion To prevent the consideration of riding a ball the the end, the rail around the lift could probably be simply extended over the lift as a third side. However, if I understand correctly, one cannot simply edit a level - it must be rebuilt. Probably not worth it. The "one tiny detail" that I mentioned earlier that I did not love: that was based on my feeling that having to court the ball onto the lift and then B onto the ball was a bit too much to ask of most players, particularly after investing so much effort to get B that far just to have the randomness of this affair force a restart of the level. A moot point now. A new observation - now that I found the underwater section - is that it is really easy to have B jump/fly off the game space when employing the falling trick from when B is coming through the building. One must have B walking in the direction of the slider and not perpendicular to it in order to get B down safely. That little detail will surely catch most players off guard and frustrate them in starting the level over. Still, my hat off to you for putting so much wonderful game play into such a small and artful design. Amazing!
@nGord Thanks for your comments, that's nice having feedback It is easy to post an updated version, but I don't think many players will download it, because most of them have already won the level in both ways and read the spoilers. I should have been more careful !
Here is an attempt to describe this level: ★★★★☆ Observation ★★★★☆ Reflection ★☆☆☆☆ Luck ★★☆☆☆ Tricks ★★☆☆☆ Skill
@chemi Thanks a lot for playing my old levels! I was not aware of all the tricks at this time so they might be kind of out of date 
Hello, Spoiler: dry ? I'm underwater but not on the lift. I can manage the last dry ball to fall on the lift (and then get wet...). But then I'm completely stuck. Could you help me please ?
@#ffffff You need to use @richardfu_ climbing trick: Spoiler once you are under water, tap on the block past the lift. Then raise the lift to one block only. Wait for B to arrive and climb on the lift. Then raise the lift again to one block. B will climb on the grass block near the win. Do not hesitate to ask me again if something is unclear. Thanks for playing this level ! How did you find it among all other levels ?
@vince thanks I understand your hint but when I tap on the place you tell me, I just get a red cross ;-)
@#ffffff Sorry I misread your comment. The last ball should not fall on the lift. Just let it fall by itself under water, then go to the draggable near the begining and use it to fall into the water. Then follow my previous comment. There is another way to solve the level but I find it harder. @B Hill explained it in a former comment: Spoiler For the last ball, do not let it go into the hole it wants to go into. Bump it, then quickly move B next to the ramp to trap the ball as it falls down. Move the platform in the water up. Then move B away from the platform one space, then forward again to push the ball onto the submerged platform and walk on the ball as it rolls forward one space. Then you can step off to the goal. No need to go under water!
Spoiler: Intended way? I drop the balls,I drop B,he goes to the final part,I do the climbing trick raising the elevator with the free camera
@meko This is the intended way, but some (most ?) players have won using another method, which is harder in my opinion, but without the climbing trick.
