MoMiner

This game puts you deep in the ground to find treasure and other fun stuff! Start off by buying any upgrades if you have the jewels available. If you don't, just push Enter to make the drill go into the ground. As soon as it breaks ground, it is under your control. Use the left and right keys to steer it, as it will keep driving down until it runs out of fuel. Try to pick up jewels, because they will let you upgrade your drill. You also want to hit fuel drums, because your drill needs lots of gas to run. If you run out of gas before finding the treasure, the game is over!
