Thanks for all the comment - I was stuck but I will continue now. BTW, the level isn't really 4x4....
The white space comment helped me out. Unfortunate R became unstable and wouldn't climb the stairs too often but that's thanks to the rotor versus a slider. Nice concise level that more like 6x6.
Enjoyable tricky level. I did manage to squeeze R up all by himself first time i won but i do like the assistance method, although strangely that made stepping off the draggable difficult.
@Frince No. That wasn't what I need. My B and R can stand on the lift, I got all ball. I need a hint for the last step.
