Balls for R

Spoiler: Trick List

B:
- auto pilot (tap and move slider to redirect B)
- springboard stairs (with B on the stairs, tap behind B and then in front of B)
- long legs slide (B's legs get longer going up stairs, if tapped and slid, then B will be taller)
- low ceiling (B acts strangely with a low ceiling and may travel over stairs that B can't normally do)

R:
- long legs auto pilot (as R goes up stairs, R's legs grow, slide the slider to another location and R may climb up)

Spoiler: Video Solution

Superb level with lots of planning then working out how to push that lowest ball without getting isolated. My method was same as video and loved all of the moves. Liked the big autopilot and the subsequent double wedge move was wonderfully flamboyant.

Only one small difference in this very enjoyable level. Thanks @Meko Guy great job!
