Dig

Dig is a 1-player arcade puzzle game for the TRS-80 CoCo.

The player controls a small character who moves in the cardinal directions underground, digging a tunnel behind him. Several boxes are located on the screen, which will fall towards the bottom if the ground beneath is removed. The player is equipped with a digging device, which removes squares of dirt vertically below them. Four monsters appear on the screen. They are initially immobile, but will chase the player if the ground near them is disturbed. The goal is to lure monsters into boxes, or drop boxes onto monsters, causing them to be destroyed. When all 4 monsters are destroyed, the player proceeds to the next puzzle. Money can be picked up for bonus points. The player starts with 5 lives.
