Tunnel Mining Tycoon [V0.78]

Updates: Y.A.P.U. Yet Another Pickaxe Update, You can now purchase "Pickaxe width", this will increase the impact on ores and stone, so you can mine multiple at once, this however, does come to the cost that per upgrade, 11% of the ores that are mined, will be lost. (0 cash, max 33%) Also, Pickaxe Power has been made 5x cheaper! Upcomming Updates: More purchasable stuff. Thats it, I guess?
