Pickaxes clink on every swing, tiles shatter on the third, gems jingle into the sack, a fanfare plays when the quarry is cleared, and light music loops underneath. These are the Owner's picks from the Audio Manager.
Imps squeak when you send them, plop into a waiting slot, and patter as they march. A soft bell warns when only one slot is left, and a sad tune plays when you're stuck (added 2026-10-08).
A Sound button (or M) turns sound and music off, and the game remembers the choice.
A Credits section under the game names the sounds' authors, as their licences require.
TREASURE!
