Feels like you could shave off 1 minute and make this a bit more challenging. 3 of the 6 continents are very straightforward, working north to south and incorporating a couple of high elevations. That leaves enough time available to type in every country in 2 of the other continents. Only Africa takes a substantial amount of time.
Good quiz. Morocco surprises. Just an impression but it was hot in autumn (25C-30C or more) and a lot of the country is arid or a desert. I remember we drove over many dried up rivers. The mountain ranges didn't look massive or cold (admittedly may be different in winter).
Fairly easy quiz. I suggest taking time off, because I did it very slowly and had a lot of time to spare. The only hard continent was Africa because all of the others were either North to South (N.A., Europe, and Asia), or had a very small number of countries (S.A. and Oceania).
All of the countries listed are mountainous. With higher elevations comes cooler temperatures. If you look at a topography map of Africa, things will start to make a bit more sense.
I agree that it was pretty easy with the time limit. For Oceania, I assumed Australia and New Zealand and then just typed random countries until I got it. Africa was the only really tricky one. Rwanda, Burundi, and Lesotho seemed the obvious ones, but it took a while to get the last two.
