Just a little remark, a few times I was just clicking "memorized" for several countries and didn't notice when it was actually a question, and clicked "submit" by error. I think there should be more difference between the "memorized" and the "submit" buttons. The game also considers French overseas territories as "countries" and uses some local flag for some.
