hey! i think your game is really interresting and has lots of potential, however i noticed alot of issues with the math of the upgrades.
i dont know if you plan to adjust this, but i definitely feel like you should consider this as i have gathered following examples.
DirtMiner: the Dirtminer is fully automatic and runs permanently unless you turn it off, which i think is a great and potential filled aspect of the game, however i realized its reward size and after doing the math behind it i discovered lots of problems with it:
a LVL 1 Dirtminer Costs 50 satoshi: this dirt Miner Produces 0.000001 Satoshi per second. using this rate it takes:
21 months to regain the investment
0.000001*60*60*24*7*4*21 =50.8032
i doubt that this is the planned value, even to make the dirtminer 10x as fast would not be enough, i think an investment time of 2 weeks should be enough.
i assume that this feature isnt supposed to be the main part of the game, however 21 months until you make profit is simply not worth it.
i do love every aspect of this game so far even if they need a bit of tweaking, with all these flaws in mind i respect the time you have put into the game.
Thank you for the suggestion on improving the system. And you are correct, the Dirtminer was not really effective for the cost that keeps increasing with each level.
I've boosted Dirtminer speed to 0.00004 Satoshi/second, which makes 50 Satoshi after approx 14 days, right as you suggested

And thank you for the kind words!

(in-game, of course)
I like the adjustment. Nice to see it so fast done. I just wanted to tell that in the "Upgrade" tab it still shows the old speed, in "Miners" it´s showing the right amount and working
