I myself enjoy this game. I think the graphics are very clean and clear. If this game was rated with stars I would give it a 3.5, and here's why:
-(According to other reviews and posts) The game NEEDS a gauge showing the amount of pollution and the amount of purity. Personally, I think there should be a mode or a button to reveal that information; areas being affected by pollution, areas clear and 'healthy', etc. And these areas should be color coded to the effectiveness of the buildings and enviroment. (in this special "mode", it would be good to include the amount your buildings are making.)
-A lot of the gameplay is very inaccurate, for example the "Nuclear Plant". In a real life situation, nuclear plants are in favor of the enviroment, not against.
-More buildings would be GREAT! and the ability to technologically advance your tools, buildings, enviroment, and custom would be a smart decision. This would allow for a more diverse gameplay experience.
I do love the game but it is missing a lot. If the devs are still with us, please see what the community has to say. Thanks! :D
(I will turn my frown upside-down when I see improvement.)
