Where there's muck there's brass, so get a shift on and head down the mineshaft to coalface number 4 and get drilling. (Much like the South Yorkshire coalfield that inspired it, this is a bedraggled shadow of what might have been, built on the bones of something much bigger. It was originally going to be an RTS-type game but spent too much time building behaviours and logic for the miners and their world so there isn't much in the way of gameplay - I just added direct controls to one of the miners and left it at that. Once you've made it to the drilling machine you've seen pretty much all there is to see, except for some fairly spectacular physics glitches.

UPDATE: Minor bug fix made post-compo to make the tunnelling a bit more stable, but you may still fall off the edge of the map!
