@Meko Guy I just realised I didn't include a trick list.

Spoiler: Tricks

Autopilot
Move B so L falls
Descend from a ball on wedge
Low ceiling

I suggest you to skip this one as you might get frustrated due to the hidden mechanism. There are two sliders at opposite end which control mech. Put the ball in and push at the right time. The red brick is where you need to tap for the ending.

@mastersifu - I think I got the hidden figured out - I de-engineered the level. I figured there was a trick list - thanks. Your levels are very obscure and throw in tricks and that becomes exponential.

@masterifu - I will be looking at the video very soon as I got to this point

Spoiler: Almost Done?

I had B in the house with feet high over and over but nothing else happened. I sent P in and nothing happened either - I'm guessing not very intuitive. A lot time spent only to fail. I was able to get that other ball in place for one more push but I don't see why? Doing that, B can get on P but nothing happens there either....

I figured it out and then I checked the video and then I thought of a shortcut - more on that later.

After spending the amount of time that I did, one must go full stars. Your intended method was very complex and involved and I did figure it out albeit after many hours.
The shortcut only needed one push of the mechanism however the timing was tight.

Spoiler: Shortcut

The shortcut is a result of the numerous trail and error scenarios to figure out your game play.

EDIT - Forgot to mention, the move at the end required multiple tests as it wasn't intuitive. As I already said, I sent B in and seen what happens (I've seen and used that move before so I wasn't surprised) but no win. I sent L in - nothing, I sent L then B - nothing - tried some auto pilots on the roof, etc. My point, should I need all those attempts to figure out the game play at the 99% mark? In order to test each, one must play thru the entire level only to find out that didn't work either . Having spectacular endings are great but they shouldn't need full restarts.

@Meko Guy .
"should I need all those attempts to figure out the game play at the 99% mark?" I got your point.
What I was thinking that time is "Having spectacular endings are great" but I didn't think of "Having spectacular endings are great but they shouldn't need full restarts." Thanks for the helpful feedbacks.
