Great app with some rough edges

Fun and educational, does what it says on the tin. Runs smoothly and has a decent number of challenges.

The visuals are rather lacking, especially when zoomed in. Map detail is blurry to the point where it sometimes makes selection of small areas difficult and impedes gameplay. Please update graphics for the retina display.

More challenges would also be nice.
