Overall the game is interesting, however because there are still too many elements that need to be added/improved it still has a lot left before it deserves to be played without a bit of cheating. I will mostly talk about the main mechanics of the game and explain what I think should be added:
-About wars: Let's be fair, current war system is so simple that it hurts, basically armies fight in the map and that's it, to be fair I don't critic this approach but I feel that the armies have it too easy to get to the princess territory and that it lacks proper rewards cause it doesn't have secondary objectives that would make the kingdom stronger (such as mines, farms or other territories that would be worthwhile to fight for even if you don't destroy the enemy kingdom).
Even more the game needs to add the ability that even if kingdoms arent just next to each other they can make war. For example something that happens every game is that the goblin kingdom and the cat kingdom go to war, but because they aren't next to each other they cant fight.
Basically I just feel that it needs to be expanded, just to give an example the holstaur territory is totally submissive to other kingdoms so it should be a point of control, having special events depending on which kingdom controls it, even to the point that perhaps a princess may want to have fun there.
-Following the last part I said I think the game lacks a bit of fun between princesses. I can totally imagine the slime princess to have fun with the human princess if they conquered the human kingdom for example, and in fact seeing conquered kingdom population being raped by the conquerors feels more than normal.
Conquest and relationships between princesses should be expanded, even more if it affects princesses that have racial conflicts (such as the mouse and the cat princess).
-Related to the player I feel that at some point we should have our own house. Even more taking into account the prices of the inn... to be fair being able to build a good mansion in which princesses could live, get guards to protect it from monster attacks and have extra scenes for places like a bathroom... would be really nice.
Albeit perhaps it isn't important to expand it so much I would at the very least ask to have a free place to sleep, the camp is quite... meh to say the least.
To be fair I can still go on and on about stuff that needs to be improved and stuff that feels incomplete (Roaming NPC's doing nothing, frog kingdom needs to become a warring kingdom at some point, restoring a princess fallen kingdom...)
But overall what I think is that the game is interesting, it can become much more interesting but it lacks on development at the moment. It still needs a lot of stuff to be improved and/or expanded. I would recommend to cheat at the current version so that you can do stuff much faster, however as the game gets more complete it would be a really nice experience to go bit by bit.
