Use a wall as a brake
If one robot is lined up but the other is not, press it against a wall. It will wait while the free robot changes position.

Direct robot
Mirror robot
Arrow keys or WASD command both robots. Up and down match; left and right are reversed for the mirror robot. A robot that meets a wall waits while its partner can keep moving. Dock both robots on the purple × pads at the same time.
Think in paired positions
Translate horizontal moves
A left command means left on the direct board and right on the mirror board. Read the two columns from the center outward.
Undo without penalty
Undo restores both robots and the move count. A hint performs one shortest-path command and costs three moves.
Fifty verified chambers
Levels 1–15 use 5 × 5 rooms, levels 16–35 use 6 × 6, and the final fifteen use 7 × 7. Every deterministic chamber ships with a replay-tested solution, while alternate valid routes are accepted.
