Open the Door!

Hummm, did I miss anything? Or perhaps I found a shortcut? Because I didn't use the second ball.
In general it is too tricky as it is based on not intuitive tricks... Thanks!

Spoiler: Shortcut?

I used clausthrophobia to climb up and then ToA to fall down and push the ball that let R cross. Climb again with R and B. Drop first R and then B on R and go to the win...

Yes i did open the door but disappointingly it led to the same basic solution as @chemi , when I initially thought that having B and R on the slider near the winblock may have led to a win there. Or am i missing something? Nice hidden door.

Ok, I found how to open the door... so my solution was a shortcut.

Can't get R out

Spoiler

Every ToA landed off the grass!! I assumed that row was a red herring but after pushing the door, R still wasn't out. Got me.

EDIT - Looking ahead, with R out I can see the win route but that's assuming R takes well to the ball move and doesn't bend over?

@gmacpro I do not think I understood. Please explain more

@hadi - No problem.

Spoiler

Does B need to do a ToA to release R?

@gmacpro Of course.If ToA is meant to fall, this seems to be the only way

@gmacpro .

Spoiler: Release R

TOA not needed. Autopilot across

@hadi - Yes ToA - means Trip on Air and fall. I've tried that numerous times and B doesn't fall on the grass? I agree, it appeared to be the only way but if it doesn't work, one must find something else.

@ridgerunner - I looked at it and said "OH!!" so that should do it. Thanks

@ridgerunner - Just tried that and yes we are off to the races tomorrow. Thanks @hadi may get another winner!!

Thanks to @ridgrunner's suggestion B was successful. I liked the level especially how some areas were revisited. Thanks

@ridgerunner Thank you, my good friend. Good explanation

@gmacpro Thank you so much. Because you play my levels and present constructive comments

Really nice tricky/logic level!! Challenging!! Thanks for sharing and well done @hadi
