So many people commenting on the the fact that newpapers wind up being the most expensive when it's been stated by the developer several times that it's intended. Also, the nerf to the upgrades slowed down everything a lot.
I looked through some of the comment and didn't see anything mentioning this, so I thought I would. The reward description for achievements is misleading. It says that the speed increases by 50%, when the speed increases by 100%.
