This game is being done the proper way, every element is conceptually sound and the game works... I could see this game becoming something huge if it is in fact still being updated and worked on by the dev. 7/10 with potential to be a 10/10 - An Idle addict
I hope you keep up with this little gem. I find it incredibly refreshing, it feels like a very grass roots type of idle game and it's quite nice. Maybe a bit more depth in terms of upgrades etc. as you get deeper into the mine.
