Overview
You have to dig, avoiding contact with Spiders, Red Faces - whose contact will make you explode - and watching for rocks that can fall on you. Meanwhile you've got to collect a number of diamonds per screen.
Other components of the game are: Green Rocks - which act as mines and explode while Spiders get close to them, Red Balls - which explode when they fall upon something, and Walls - which come in two types: the ones the explosions destroy and the ones that are undestroyable.
The Diamonds are in fixed places on the screen, but they also appear when a Red Face or a Spider is destroyed.
