> Thank you! Once I saw this comment, very satisfying puzzle. At first I was fumbling my way through randomly, but around halfway I started to visualize the board as two "sets" of connected paths and grokked how to switch between them using the lower-right quadrant.

Exactly this - I used the upper right quadrant to switch lanes, but the idea is the same: if you cannot reach the target in the current lane, switch lanes and try again.
