This app had a really good general idea that I think I could've liked playing. However there are not near enough details in the instructions. They tell you enough to get you started out after that you have to figure out what to do with very vague instructions. I mean I had no problem figuring it out but it did require some thought & just trying some different things. I gotvery frustrate when my city burned 3x & I couldn't figure out how to clean up the last little bit of pollution I had left
