Mine Shaft
It’s business as usual down at the gemstone mines… or at least it was, until
your trusty mining robots started going haywire and wrecking equipment. Rather
than cut your losses, you decide to stick around: can you excavate the
crystals from each mine and make a hasty exit before the dysfunctional robots
destroy your mine cart?
The action takes you down to the twisty network of passageways inside the
mine, where several gems are strewn about waiting to be picked up. Soon enough
the robots arrive and start running amok, chasing your mine cart along the
twists and turns; any contact with them will cost you a life. Luckily (and
somewhat unusually, for a mine cart) you’re equipped with a gun to shoot them
down. When you either collect all the crystals, or hunt down all the errant
robots, the exit will appear: pass through it to move on to the next level.
You earn an extra life for every level cleared, and the robots in turn
multiply and get faster – later levels introduce new enemy types, including
the dreaded (and bullet-proof!) skull.
