This game in a nutshell

It's a casual mining simulation game called Dig Deep (Korean store name: 땅을 파자), developed by CrazyLabs for mobile and PC. It's an idle simulation game where you dig into the ground with a shovel to mine gold, diamonds, treasures, and more. You hire workers and upgrade equipment to dig deeper underground and expand your mining company. It's available on mobile and PC platforms. If it weren't for the mid-game ads, it would be a great game to play mindlessly, but the mid-game ads are really annoying.
