Click the block to earn Cash. maxPro is the amount of ore you have. maxProCost is the price of an extra maxPro. So far the best maxPro is 16. Anything after that will get bigger by a bit, but you will not unlock new ore, and you won't get as much money. maxProCost may seem surprisingly high at price, but later on that will be worth nothing to you.
I did use some ores from the game Minecraft, but most of them aren't in Minecraft, and are made by me.
