this game is really fun! although, I would want to give a few suggestions. first, make a system in which you can suggest allies to do something like build a port, build military and etc. Second, Maybe you could add a system to kick allies out. Also, i noticed a bug where if you are already in a map in which you are already in an alliance, you cant expand your faction across borders. Those are my suggestions for now . If you decide to implement this it would be really appreciated!
