Long Way 'Round

Thanks for the rating!
Which ball rolled away on you? I was finally able to watch Don G Rowe's Design Lesson exploit video, now I know exactly what autopilot you referred to, it doesn't bypass anything hard. So I'll leave it.

Spoiler: Red Herrings

There should only be 2 red herrings:

• 
  *The ball on side 2 crammed into the corner. I just like watching B get smooshed. This ball will either go nowhere or roll away.
  *Most of the traffic, but I consider that one big red herring.

@gmacpro Interesting, the ball on side 3 stays put for me almost every time, in the future I'll block all for sides.

Arrgh! I see why you think R has no use. I downloaded my level and played it that way, I think Mekostudio (or the way I used it) removed a block. This happened on my level Cistern as well. That two piece slider shouldn't reach B.

Spoiler: Solution

B should be stuck on the stone pillar at the entrance to side 4. You then block R near the zapper forcing him onto the roof. He walks over both rooftop rotors, entering traffic with the 1x3 vertical slider. Now just get R to the win.

I'm done. I give up!
