Cuthbert Goes Digging

Cuthbert, Microdeal’s mascot, is trapped inside a mine, filled with crawly
creeps. He must climb the ladders out of the mine and reach the surface before
the oxygen level reaches zero.

Each floor in the mine is filled with creeps, and Cuthbert’s only weapon is
his mining pick-axe. Using the axe, he can pick holes in the floor that the
creeps fall into. Trapped in the holes, they are defenceless against
Cuthbert’s axe. Once Cuthbert has reached the surface, he goes on to the next
level.

As you may have figured out, Cuthbert Goes Digging is essentially based upon
Space Panic.
