This mining game is amazing for early access I can't get enough of it. I have played many times and am still trying to get past day 26 I just can't get the 5000000 coal to get to the next day yet I know its possible. That keeps me engaged as that competitive side of me wants to demolish all the ores and somehow get them to the collection box before the day ends. Oh I saw secret codes but haven't found anything online regarding those or on the discord where might I get my hands on some of them goodies? Could be because its still in demo stage but would love to test them out ya know for the sake of testing things out not for my own coal empire endeavors. Great game 5 stars from me highly recommend!!
