Okay, first off let me confess the following; I like the Demeter update, the .23 update is making sense now, even taxes are a good idea and MU's are a godsent for people like me, who like building more than getting lost in dark caves. That said, let me get to the point; The mining minigame and it's entire game-loop is a mess.
instead of taking the mining part out of your hands, it just ties you up moving all over (no VR) to make you carefully calibrate MU's (tedious job and calls for spreadsheets of min-maxing. To solve this problem, I can think of a lot of solutions that would probably piss of other people or be downright impossible but IF we want to keep this system working, there is only one medium where these kind of click-bait, repetitive and dopamine fueled games have a place, on your mobile.
Let me update the calibrations from an app while taking a break at work, or in the train, or in bed or wherever. Let me play the real game when in the real game but just hook up a small website or app with a simple API to the game that takes care of the few steps needed to update the calibrations. I can time them better, feel less... well I think it speaks for itself. Thanks.
