For the creation achievements, could you possibly put how many you've made out of how many so that it's easier to tell how many you need to go in order to get that particular achievement. I recon you could do that for the rest of the achievements to make it easier and faster ya know.
I can see a 'sell all' button making this game funner/more effective. If you do end up having an 'offline computer mode' then might I make the suggestion of making an automatic computer selling upgrade. This might also reduce the need of a 'sell all' button, and you can sell things offline. Just a couple thoughts to shoot your way.
When I load up the game all of it is grey except for a black box to the right with some grey squares in it, and 2 orange blocks to the top with some vertical grey lines through it
I have a suggestion, using the gold bar things for upgrades, maybe having to spend x amount of bars to give a certain percentage to one of the groups, for ex. 2 would increase miners output by 5% then 3 bars would increase the base output by 7% and so on and so on
What does the, I'm assuming gold bars, do? Other then that it seems like a cool idle game. Maybe add a couple things here and there to give special bonuses when you hit certain milestones if that makes sense.
