Green City is a puzzle game, where you have to build a small city.
In each level, you will need a set amount of the buildings available.
In addition, you will also need to keep the end of the river, flowing through your
city clean.

If all goals are achieved you have build a small city, and kept it "Green"
and you will proceed to the next level.

Also you can build parks. Each building standing next to a park will become "Green".
For every green building in your city, you will gain one Green Point.
Try completing the level, with as many Green Points as possible.
