I like it but the constant repetition is really grating. I know its probably some fancy duolingo style idea about proven science but its really grating to have to confirm that yes I know where canada is every second click - only one in maybe twenty or thirty is interesting or difficult and having to spend ages to get to that point is annoying. Especially before I saw the option to turn off tiny islands so I just pressed on greenland every time it wanted monserrat because its not worth trying with the overlapping circles in carribean.
