Nice! I always wanted to make a 'crosswords' quiz but never managed to find a decent idea. It's not necessary but if you manage to have 'ticks' appear for the continent/capital-country you guess I think it'd be even better
I still wish this quiz to have only 12 answers (as words), not around 100 answers (as characters) like this, but it might be impossible to do so because of intersection letters. :(
Please make a checklist for each continent, for country and capital. It was hard to keep track. (This I mean add a new column and put a check mark next to each of the 12 "unique" letters [letter that only appears in one answer]. That would be neat. :)
