Hm...Game play. I'm going to jump all around, so forgive me:
When occupying Russia, one can also attack Lithuania and Poland (I.E. "From" Kaliningrad), yes? It's not exactly clear if it is yes, but I'd assume it will be clear in the dropdown menus. If yes, then it also makes the territority Russia somewhat strategic, if only because you can hop past Belarus and Ukraine into Poland with possible
slightly quicker expansion into Baltics, Central Europe and beyond.
The attack route between Faroe Islands and Denmark almost seems improbable, due to the seemingly large distance it covers. But I understand it is there to keep Scandinavia from becoming a linear continent.
Transcontinental has 2 borders, Russia and Turkey, yes? With 5 countries, I'd knock this down to a bonus of 3, considering the only two borders I see are also pretty darn strategic themselves (I.E. look at how many places you can attack...5 different bonus continents.
Hellenics look similar to Baltics and Benelux, 3 territories and 3 borders each. Have you made Hellenics a Bonus of 1 due to the role Cyprus and Crete play in the Med. Islands bonus? It seems like it might be worth 2.
Central Europe could perhaps be a 3, if you knock down Transcontinental.
Western Europe looks pretty nice and strong. Take a look at its borders and easy exanpsion possibilities. It has 3 borders, yes? France, Corsica, and Balearics. Now, Western Europe has a wonderful possibility to expand into Sardinia to limit it's borders to 2 for Bonus of 5. It could even expand to Siciliy and keep 2 borders with that 5 bonus. Now consider if you take both Sardinia and Sicily, you basically can grab Malta while your at it because it is a dead end.
Now...what do you have here? Well if you've managed to hold Western Europe (+5), and have managed to capture Sardinia and Sicily and Malta, limiting your borders to 2, you also hold 5 Med. Islands for an additional bonus of +3. In summation, you have 2 borders, for a bonus of +8, with 11 countries (I.E. you'd probably pick up an additional army from random territories around the map). This seems kind of strong, yes?
Possible ways to alleviate this. Make the Crete attack route to Malta rather than Sicily, so you can't use a dead end Malta to grab easy Med. Bonus from Western Europe. This keeps the Italic States still with 3 borders.
You could even consider adding a route between Italy and Sardinia, but that might just be adding too many routes in the general area.
I'm sure there are some other ideas too, I just haven't thought considered them too much.
(Note: I very well could be wrong in my above analysis. I often misread maps while looking at game play, that is why my score is horrible.

So if it is all a bunch of bunk, forgive me. I tried at least.)
Regarding Graphics:
Could you improve the route between Scotland and Northern Ireland? Maybe nudge the name a little left so it is clear that the route is not connecting to the Republic of Ireland, and swoop the attack route a little more in the north of Scotland.
Some of the route dots are inconsistent, or appear that way at least. Examples: To the right of Iceland, there seems to be a larger dot at the end of both routes, and the same appears south of Faroe Islands. Perhaps if you make where the route "attaches" to land a slightly larger dot like those, that'd be fine, otherwise make them all small and uniform like the others.
