Twosome

@yuan - The ball between the 2 stairs idea wasn't taken from your level '170318' posted yesterday as I had this level done weeks ago.

At the start I skipped quite some moves as you can let R push the ball. Did things in different order after that but mostly the same. Thought there was no claustrophobia possible to return B to the start, so I used a momentus sideways springboard for that. At the end the ball didn't cooperate and I miss tapped and B got zapped. Watched the video assuming I was doing it quite wrong, but not so much actually. 5 stars for a clever solution, though I don't like the ball at the end.

@Block builder - You are right about the 1st ball. I tried that but R just spun the ball but if I let R keep hitting it it finally fell. That makes the level very doable as the zapper tap and land on R was forward thinking. A shame the last ball gave you trouble as I didn't have any issue with it. I did (sometimes) need to get B to run at it a few times. Thanks for playing and commenting.

@Block builder - Forgot to mention that there was claustrophobia for B to return - the rail for the slider where B starts provides this.

Took a while to work out how to push the high ball. My start was much less moves than the video and i used a side stair step in the middle rather than autopilot. Really liked the gameplay to force bots to turn right in the winblock corner and I experimented and did it with either bot leading.

@ridgerunner - Thanks so much for playing and making a comment.

Believe me,I was sure that this was the intended way....but I was wrong

@delator77 - Yes - that's how @Block builder did it too. I guess I didn't wait long enough because when I tested with R, the ball just spun. Thanks for playing and commenting.
