ECHO

Drag a ball to move it oe square. Every 3 turs, EVERY ball you moved repeats its move — the brass dial at the top couts dow to the ext beat. Balls break gems of their ow colour. Break them all before your moves ru out. Press WAIT to skip a tur ad let your machie do the work. ERASE removes oe echo if you chage your mid. Desktop: drag with the mouse, or tap a ball ad use the arrow keys; SPACE waits.

Every move comes back. Drag a ball and it slides one square — then, every three turns, every ball you have moved repeats its move. Forever. Balls smash gems of their own colour, so you are never just solving a puzzle: you are building a machine out of your own past, and then watching it work. Line several balls up to strike on the same beat and the whole board goes off at once. 160 levels, every one of them verified solvable before it shipped, plus a Daily Echo that changes at midnight.
