@Meko Guy That lower section took a little work, especially the ending. Originally I had B herding the R pair right up to the end, but the stack was unstable when going around corners.
I won using B the same way as @Meko Guy shows in the video. I also can't figure out how to get a win using the two balls that B left alone ...
@Don G Rowe I changed too many things around, unfortunately... if I had left this puppy as it was originally, it would have been better.
I don't generally replay a level after a win, unless I really messed things up and was able to envision a win with a no-waste path. I was able to slim down the path and shorten my time. Then I read the comments that 2 balls were not needed; I worked it without 1 easily, then with extra effort, the two. I liked discovering the variety in play.
I won with B, and then with R (no tricks) but still did not use one ball ? Lots going on in this level and I enjoyed having Bots running all over the place at the same time. Lol
