The game consists of a large maze of which only part is
displayed on the screen at any time. The tunnels are filled with
soil and boulders, in some places there are mushrooms or weeds.
The object is to dig through the soil and collect the
mushrooms. At the same time the Wrightoid Robots are
hunting you out.
If you move below a boulder it will become dislodged and start
to fall. If you happen to be below it then you lose a life.
The weeds always grow into any gap left when you move soil.
This creates an impassable barrier.
To help you get past all the nasties, you are armed with a
limited number of time bombs. If you don't get out of range
before they explore then you go up with them.
The quality of the game is high and keeps the player interested.
