Spoiler: Trick List(in order of use) - auto pilot with low ceiling (note the brick) - springboard stairs - auto pilots Spoiler: Video Solution
Spoiler At first I was confused how to start. But there are red bricks, which must have a purpose. I like the low ceiling effect here.
After getting the ball to the beveled slider nearby the starting point, I desperately tried wiggling the slider every which way and even bumping the ball with B, but everything I came up with was for naught. I ended up having to watch the video there, and felt really foolish for missing that solution whenever I had seen it at the beginning of playing the level the first time.
