The biggest flaw in this game, as I see it, is the irrelevance of the workers gps. I only upgrade them, when nothing else is available... currently 25.1 mm gps, which comes from workers - 35 LL gps, equipment bonus 25.1 mm gps....
Hy :)
Really cool game :)
Just a suggestion:
After a time, I find myself nor upgrading gold/click ( after I reset the game) for a longer period :)
I wonder, can you add a Max lvl up button, which would upgrade it for all the gold I have?
