Your fields have been invaded by burrowing killer bugs. You must eliminate the bugs by trapping them so they can't move. If you accidentally uncover one of the ravenous bugs it will devour you immediately.

The graphics is not only flat but presented in glorious monochrome black and white.

Basically a Mine Sweeper game but with the added feature that the bugs move about. Which means that the playing field is constantly changing. Since the bugs are moving you have to reevaluate where the bugs are hidden after each move.
