I love it! Addicting way to get kids thinking about bigger humanitarian issues

I absolutely loved this app... Once I got it to actually work. At first I was disappointed because I couldn't get it to load. Tried uninstalling and reinstalling it. Eventually I got it to load, but basically you have to be EXTREMELY patient and just wait for it to move past the screen that shows the developer name. Anyway, once you're playing you immediately get a beautiful gameface and a game that lets kids try different actions to help make all the regions of the world more "green," meaning give them enough fresh water for their populations. Use money to do research or build plants or pipelines. Develop a strategy that gets water everywhere evenly. Yields hours of game time and feels like it's happening in "real time," because every minute, something is changing somewhere in the world.

Disappointed on iPad

Daughter loves this game but it won't run on on her iPad with iOS 9.3.5 despite the specs which say iOS 7 or higher. Starts to load and then just dissappers.
