Hi,
I would like this game to allow us to use the keyboard more.
For example;
Upgrading mines is a tedious work so I often just do not build them (iron mines specifically).
It would be super nice if I could just click on one, pred "arrow up" to upgrade, "return/enter" to confirm and press "tab" to move to the next mine.
I think it would take some of the annoying things out of the game.
Cheers,
Koz
