Yarg treasure coves!
 

Why not have more fun with the shovels?
excavate little tunnels in the soil and get to a level underneath Gk, its a great transport system, and riddled with monsters to kill.

could be quite fun, something to do when your bored,
course it may take a little while to get there,
like 30 shovel fulls?

Also be a cool level to reintroduce the draisines (small 1 manned train items)
which had a direct rail system to the mines and such,
