Hello, thank you for the game I love it! I paid for it to support you and I'd like to give some feedback :)
It feels pointless when a state with 1 territory is announced to shrink but nothing happens. I think microstate should be eliminated during that event.
Some states expansion are unclear. Maybe an island that does not appear on screen gets taken, but it feels like nothing happens sometimes. Maybe some adjustement could be needed there. Also, islands could have a circle drawn around them with the name of who controls it to make it more interesting for island nations and colonization later on.
Some annexation take territory according to modern day borders. For example, Finland lost territory to Russia. Then, Sweden annexes Finland but Sweden also gets the territory that Russia got earlier. If Finland had taken territory from Estonia before the annexation, Sweden would get it, so that works at least!
I bought the game yesterday I will probably give more feedback, love what you do, have a good day!
