Mustached Driller is a mining game in which you play as a character with a mustache! Dig your way through the ground as you search for coal, silver, gold, emeralds, sapphires, rubies, and diamonds. Sell your minerals for money at the buying station; the rarer the mineral, the more money you will receive from it. You will need to dig deep to find the rare treasures, so upgrade your gear with your earnings and try to find keys to gain access to greater depths. Don't forget to visit the cafe when your energy is low from all of that digging!
