Or just Spoiler Toss R onto the slider by the win. You must plan more carefully Grasshopper, now that you have learned tricks.
I gave up as B missed the last auto pilot with the half pillar and ended up on the stairs. With NO WAY to recover , I wasn't doing the entire level again because of one tap that was too fast/soon. As a side bar, on my first two attempts, the half pillar stopped working, not sure why so even if B made it to the end, B couldn't get to the win.
