I am enjoying it! Besides the other feedback that has been raised and addressed already, on mobile (Android Chrome) the instructions say to drag the circle, but the behavior is that the circle jumps to the point of first touch; more of a "click on the country" behavior than drag. But that's minor. Really fun project!
