THANK YOU FOR PLAYING! Glad you liked it! ^_^
You place construction sites for free, you have to have a person on the site slowly provide the wood to build the building.
If you have people on a construction site and you have people on a woodcutters house, then you'll be gaining one wood and losing one wood at about the same speed. Maybe that's the confusion.
We definitely need some progress bars and some "got wood" sound effects.
