I'm would give 0 stars but I can't, so it got 1. Got to the modern mill decently quick. Literally been stuck there for days now. Everything has been upgraded to as far as I can go, all my stuff is backed up, nothing is moving. I'm not spending my real money on the game sorry. There's no way to move on, other than spend real money or wait months to maybe, possibly move on. I'm not waiting that long either to move on or spending money. So I'm deleting the game.
