Even though I had a shortcut win, the designed gameplay was worth full stars. I did spent some time looking for the designed one but failed to spot it as one of the assumptions of the designer is false which allows for the shortcut. Spoiler I didn't need the three bot stack nor the ball that roll between the zappers. I had the same start where B autopilots onto L bot head. Then B can stand on the rotor and spin up for the star ball push without being tossed out of the map.
@ohmytian - Again more skill than I as I wasn't able to get B up. Good for you. Thanks for P, C and R.
