Subterranean vs Terrum DeepDrill

Dig deep in a retro pixel world and see how far underground you can go. Control a small mining vehicle, dig through the earth, and uncover gems, ore, fossils, and other valuable resources. Sell what you find, upgrade your vehicle, and head back down to dig even deeper. Improve your drill, light, cargo, temp, fuel, and hull to stay underground longer and reach rare riches hidden far below the surface. Inspired by classic mining games, this 2D side-scrolling adventure is easy to pick up and satisfying to play, whether you have a few minutes or want to keep digging just one more run. Dig, mine, upgrade, repeat. How deep can you go?
