Imp groups, bigger quarries, imps seen from behind
Imps now come in numbered groups. Tapping a lane sends its top group, and every imp in it with a tile to mine marches out at once. The rest wait together in one slot that shows how many are left.
Each lane is a single column, top group first, so it's clear who goes next.
Quarries grew from 30 tiles to as many as 80, and the cells shrink to fit a phone screen.
Imps are seen from behind as they march in and swing, then turn to face you and leave with their sacks. Waiting imps walk out of their slot instead of popping up from the ground.
Tiles are crystal ore and break into cut jewels, after the Art Director's style reference. The color symbols are gone at the Owner's request, since later levels will have more colors than shapes.
TREASURE!
