In Untitled Drill Game, you can drill out various Ores, each having their own rarities. You can then sell these Ores for money and purchase new Drills and Hand Drills or you can use them to craft Drills or Totems.

Weather

Some ores can only be drilled when certain weather is active. There are total of 4 weather types:

Day
Night
Rain
Blizzard

Weather can be changed with Weather Totems which you can craft or purchase at the archeologist for Robux. The totem will change the weather for 6 minutes.
