This game runs entirely from your browser.
Any public service has a maintenance cost, for you to pay. A house, a industry, or any other private initiative will be built only if there are demand and manpower. So, if you want more factories or shopping centers, create more residential area and let the population to grow.
Pay attention! Pollution will appear fast with your city growing. Trees can save the population and your job.
You can change some game attributes by accessing the land
object at the javascript console. Try to open the javascript console
pressing F12 key or some browser menu item, then run:
land.money = 1000000 (the status information will not be updated until the next month)
Some day some building will be destructed. You have been warned.
