Echoquay — Game guide

Your goal

Coordinate two robots across 24 harbor puzzles: cyan moves immediately, amber repeats your last command. Collect their own crystals and reach both docks. Later chapters add pressure plates and bridges.

Tips to try

  • Check the stored echo before choosing your next direction.
  • A blocked command is still remembered; use walls to adjust the robots’ timing.

Questions about the game

What does Wait do?

Cyan stays still while amber carries out the stored move. The next stored command becomes Wait.

Can I undo a mistake?

Yes. Use Z or Undo without a limit. Fewer moves earn more stars; there is no timer.
