And South Africa completely takes over Lesotho when you type it first... not sure if that is supposed to happen because Lesotho is so small though. Either way, great quiz! (Though it is fairly easy if you only do countries bordering each other)
This is a result of taking a shortcut when the world SVG was made. Since Nepal and Lesotho are landlocked, the paths for India and China and South Africa are drawn correctly but the maker wanted to make a shortcut, which was pretty smart, but in this quiz it uncovers it. This is also true for Macedonia and you can see it in "Countries with an Empty Map"
I think if you're going to show Palestine, you ought to list Palestine as a nation. I know it's a political landmine on this site, but they are given far more diplomatic recognition by other nations as independent than Taiwan (ROC), but a few less than China (PRC)
Why do some island countries have the round dots (Malta, Maldives, Mauritius, oceanic countries...) but some don't (all the Caribbean ones, Singapore, etc.)? Would be better if all micro countries get the round dots.
Not very difficult if you know what all the countries are. Maybe consider removing the answer box at the bottom so you can't see where the countries that you are missing are located? Having the borders be shown after you guess the correct answer makes this much easier, so I think this would give more challenge.
