Let it run and idle!!! Sell stuff sells your current layers materials. Up pick levels up your pick and makes it faster or more efficient. up type ups the type of material you get, but it sets mining efficiency to 1 so essentially late game it is so that you can not click the sell 10000 button two billion times You can show/hide all menus using respective buttons.
This took forever to fully playtest. Without cheating of course. Version 1 slight glitches and only two levels. Most notable major glitch is when you go up a layer. You have to close and reopen menu to change the variable. Version 1.1 main bug fixed Version 2 New level
