Left-Click and your Pickaxe will come to the red dot. Press Up arrow to show stats and Down arrow to make them go. The more tunnels you have dug, the more rarer materials appear. The 3 materials are Coal, Gold and Diamond. More Coming Soon! The 4 Rarities of Pickaxe are Common, Uncommon, Rare and Epic. The more materials you gain, the more your Pickaxe will improve. Every time your Pickaxe improves, your Harvest Multiplier goes up and every time you dig up materials your gained mats will be multiplied by your Harvest Multiplier. E.G: When you dig in a tunnel you normally get 1 material, but if you have an Epic Pickaxe and a Harvest Multiplier of 4, you would get 4 mats as 1 x 4 = 4.
