I looked over the oblast names, and they are all correct, in fact maybe when you made the game you provided the localization for Russia and Belarus intentionally, in the languages of those countries, and not in Ukrainian 

p.s. I do not speak Ukrainian either

  hello,  

it's a neat little game, runs well   , i want to thank you  and also announce here publicly that i am the GRAND CHAMPION of the leaderboard sviatoslav igorevich , the great prince of kiev, who ran roughshod over the demonic slave-raiding khazar empire so that for centuries the SLAVS dominated the steppe lands,  the great PAGAN prince of rus' sviatoslav, the inspiration for centuries of ukrainian (and even russian) nationalists

one problem - in the ukrainian localization (with the cyrillic names ) some of the names, i have noticed (and maybe more of them) are russian, instead of ukrainian

like Россия instead of Росія

Беларусь Білорусь
