Angular Building

@shultz Thanks for playing friend . Nice to see shortcuts, and I neglect accidental shortcuts. And the extreme shortcut you mentioned in the first comment, seems to work. But my level always are not simply about the winblock, it's about all the stars, I would like to mention my previous level 'B Patient', and I would request you to play it, where you can win very easily by capturing winblock, but there is some more gameplay for other stars .
Again thanks for playing my friend .

I was able to beat the level without the video solution! I got lucky, I did not figure out the ending in the video solution.

Spoiler: spoiler

For the ball by the spinner, I knocked it down, and got it to fall through the hole in the roof with the slider pulled out. It fell to the first floor, and rolled very slowly towards the hole that dropped it into the winning position gap.

I left L up on the second level, I didn't figure out to knock him down to the first floor. I thought he was supposed to stay on the second floor to guide the ball into the hole.

I was then able to drop B with an autopilot into the same hole in the second floor. I didn't discover the drop using the spinner until the video.

I really enjoyed the initial gameplay, a really good challenge, and I like that most elements had multiple uses. The two shortcuts and the tricky ending are why I chose 4 stars.

Edit: The ending is still a little tricky for my skill level, but I changed the rating to 5 stars, because I enjoy replaying this level!
