We Must Dig Deeper

Tunnel through the earth in search of precious minerals and return to the drill rig before time runs out! Do you stay close to the drill rig and collect lower quality ore at a safe distance, or risk it and go for the more expensive stuff at the outer edges of each map? Get back in time or else it's game over!

THIS GAME IS A PROTOTYPE AND IS NOT FINISHED/COMPLETE.
