At the bottom of a hole

More games, though I'm just teaching this one and popping in occasionally to view the progress.  

This is Sub Terra, a cooperative caving game involving cavers with different skills trying to escape the slowly-revealing maze of the cave they've fallen into - trying to avoid getting munched by the occasional monster that lurks down here.  

At this stage everyone seems alive, if not exactly in the best of health.  A situation that doesn't last...
