Another feature! Congratulations! :) By the way my 'Revealing' quiz is very successful. I have another revealing quiz done and hopefully released soon!
I assume it is because Singapore's lakes cover a higher percentage of its area than lakes in most other countries, so it wouldn't make sense not to include them in its shape.
That was interesting, I've never seen a detailed image of Singapore. My brain went to Monaco/Benelux/Caucuses due to the jaggedness & ports. I always forget that Singapore is an island. Thanks for the quiz
