It's really very good. Time to time should be added new content such as rivers, mountains, glaciers, deserts, forests and other topographical relief features. Disputed territories should be mentioned so that it may not hurt the sentiment of the people belonging to that particular regions.
You should be able to select countries that the game wont ask (eg. United States or Canada). Pretty much everyone knows where those countries are located, so it bit irritates me when the game asks for countries like those (as I already know where they are located). But otherwise this app is very nice.
My first goal is to learn the names, locations, and flags of every country in the world. This app has been perfect for this goal. I think it really helps to have to find the country on a world map. Great for spatial learners. Only thing I'd change is the projection of the world map - the one used is in mercator's projection, which distorts the the top/bottom areas...but I'm nit picking
While scrolling country name, It's very sensitive. Add country's rivers flow path also..
It's really No. 1 learning game.
This game is exactly what I wanted, please put the currency information too. You guys are amazing.
