Mildly Entertaining
What Dreadful said, you're missing Montenegro (I got Serbia wrong because the incorrect map confused me). Also "Former Yugoslav Republic" is actually Macedonia. I know some people call it "The former Yugoslav Republic of Macedonia" because the Greeks claim the name macedonia as well. Use Macedonia like the rest of the world (unless you're Greek). Thank you Wikipedia
Otherwise it's okay, the graphics are good, and I like the feature of highlighting the correct country if you've made a mistake.
