Capitalle - new online geography game

I found this game today I think via Metafilter.  The game chooses a random world capital city and invites you to guess it within 6 tries.  After each guess you are informed whether your guess involved the correct continent, the correct hemisphere, whether the city is coastal or inland, how far off your guess is in term of distance, and whether the correct answer is a larger or smaller city.

So, in today's game my first guess was Kinshasa.  I then guessed Lima for a southern capital in another continent (forgetting its coastal location).  The final stage was to use the distances (see map at top of embed).  Sucre was closer, Asuncion even closer, but Buenos Aires further away, directing me to Brasilia.

I had to use a map for assistance.  

Sorry for providing a spoiler for today's answer, but you can go to the Capitalle app home page and click the "practice" button for a different random capital city.
