Not obvious at the start how to get these high balls so it was an enjoyable challenge. My gameplay was almost identical but i messed up at 4:30 first time round despite using a stack as protection against an overshoot. But i had not raised a draggable which is presumably more important as it worked next attempt with it up. This was a great move.
... think hard to get B ontop of L to push balls, turned out, its L ontop of B, where B travel around bringing L.
Excellent tricky level... our remarkable difference was that... Spoiler to do the second stack you used an autopilot with B to the wedge/draggable to advance the position to L...but as my B is really fast, was able to turn around and reach the desired position before L thanks for sharing & for the fun @Meko Guy
