This quiz is fun to attempt but even with one hour allocated (the maximum, I believe), I did not have enough time to finish - around 40 countries still to go - which is frustrating. Maybe if you were to cut it down to the top 7 or 8 cities per country, it would work better.
It would also help if you were more lenient with spellings: e.g. I tried Klagenfurt, Rostov, Yekaterinburg and Santa Cruz, all to no avail.
