A slower game, and a chest that fills with what you mine

Everything moves at about two thirds of its old speed: walking, swinging, gems flying and crates.
The treasure chest sits at the top of the playfield instead of beside the quarry, so the quarry gets the full width.
The chest fills with the gems you actually mine, in their colors, row by row from the front, and is full exactly when the quarry is empty. The gold heap is gone.
