Ember Reliquary
Couple opposing row gears, lift a column, then lock each elemental seal out of the mechanism.
How to play
Seal column1 with three Ember, column2 with three Tide, and column3 with three Moss. Turning a row left also turns the NEXT row right (row3 couples back to row1). Sealed columns are skipped by both gears, changing the puzzle geometry. Two halo charges lift an unsealed column cyclically. Seal matching columns for free. Undo restores the entire previous operation, including spent halos and sealed columns. There is no timer or move limit: try to finish with fewer operations and save a halo.
Tap action buttons, or Tab and Enter/Space. Directional games also accept arrow keys. Coordinates are row:column. Restart returns to the exact opening state.
