Gold Miner: Drill Empire
Break rocks and golds and stack them to the mine cart.
Dig whole towns to expand to new lands. Each rock you can destroy, can be exchanged into money. With money you can add new carts to help you mine. More carts, much higher levels means more money and easy development.
Easy controls, with just Tap&Hold you can move your cars. And by clicking carts you can expand your miner fleet.
