Hello, first thank you for the game, I play every day and have fun / learn a lot.
My mystery country today was Spain. One of my guesses was Morocco, which left me 20km from the border of the mysterious country. At that moment I even thought it could be Spain across the Strait of Gibraltar, but since the cities of Ceuta and Melilla are Spanish territories and form a land border between Spain and Morocco, then I ended up being left with the possibility of being the United Kingdom (for account of the peninsula of Gibraltar), which was wrong according to the game.
