Economous is a game i'm working on. It is currently in developement (VERY EARLY in developement, which you should know. You should be surprised these versions are even public.) There are two items, a tree and a factory, and they both produce items. The tree produces 3 wood per minute and the Factory produces 3 Spark Stones per minute. Each minute, they say "collect!" and you click them to collect resources, which you can see in the menu in the right. If you have a mouse that can middle-click (click with the scroll wheel) then you can use the scroll wheel to drag the tree and factory around the island.
