Yes, I like the concept in general. I understand that the game still isn't finished. I would like to add some of my ideas. I would like to see an option to continue the game after you conquer the last country, even if it is just to see all the character interactions, especially the one from the last country you conquered.
I would like to see the military and economic system expanded. Now it is very easy to conquer all countries very fast. I would suggest that you would build up "Military Strength" as a point system that would automatically increase per day, is affected by decisions, can be bought with gold or eventually can be increased with are more extensive kindom building system (like buildings or a country management screen). Those Military points could be consumed per attack or if you fail to hit targets in the mini game.
Conquest also has no negative consequences. I would suggest that new conquests would lower the people's happiness, as the new people in your empire would be unhappy with being conquered. I would also suggest adding the option after you conquer to either plunder the new country (more gold, less happiness), only plunder the palace (a reduced amount of gold but the happiness only decreases a little) or to rebuild the country (you have to spend gold but gain happiness). That would make gold more important as I had no Gold problems during my game, even though I almost always choose the expensive decisions.
