If you have a suggestion as to how this might be changed please do a remix! You could add your own building to this city generator. Just make sure to increase the random building selector number by one.
Thanks to chippering for this. I used the building population code to do the same with tree images from Google. I duplicated the cloud with variable speed, added a static moon and changed the background for a night effect. In the end I used the rain sprite by "Make it rain ANYTHING you want! remix" which was remixed by multipixeltwo.
