Really tough, but very enjoyable! In hindsight, I see now that one should keep in mind that the white space in the rest of each country's square is still part of the country, and that helps paint a clearer picture of the shape of the country in mind as it provides a rough idea of the population distribution. That would've helped me a lot on China as the country shape is nowhere near apparant from the red dots alone. Same goes to Egypt and Canada.
