Simple Level

I'm so glad to see you back on the forum!!
Since I saw you were the author, I immediately knew your "Simple" level would be incredibly difficult!
I racked my brain, but I think I've figured out the right solution. But it's not working for me
(I can't get the timing right, so I'd like to see your solution)
, so I had to come up with a "new move". And it works. Here's my solution:

Cool level. Thank you

• You just need to make R turn right when going down the stairs by causing a collision between B and R and

let R push the second ball not B.

@XSHY Thanks for your reply. What you wrote is my final decision. So, in the end, I did everything right.
I was hesitant because there is a workaround and it's well-designed. I initially thought it was necessary for gameplay.
But now I understand:

that it serves to show that B can't possibly run that distance in time to turn R onto a longer path. But I spent a long time trying to create a sticky effect to make it happen. If it weren't for the tree, it might have worked. But you thought it through well!! The tree is in the way. I made many unsuccessful attempts because I know you love this move—cutting off B's long path (a bug move).

Even after doing everything, we cannot reach the winning block.That's a good thing.
I will play a few more times and see
