Altough this is an under development build (v0.13.4); this is by far the best H-RPG game I've ever played.
It has a pretty good character design, that really stands out even with the game's cartoon-ish art style. The characters are a mix between cuteness and sensualness, making a really good combination.
The music could be better, but it does its thing by giving the game a retro ambient that goes with the maps pixel-art style.
The gameplay itself, features an ABS battle system; bringing a fairly fun experience when battling, or even when grinding! The quests are simply awesome, as they are not monotone at all and even come with some minigames.
Also, there is a "progenysm" system that lets you have children with princesses, with an IVs system that would bring back some memories of Pokémon games. Did I mention that there's more than 60 possible custom features for each children you can have? That number varies with each race, but yeah, 60 is the minimum.
There are some other details about the game, like random bugs or the boring travels from a region to another, but those things don't really ruin the game experience. And since this is a game in development, things like that can be fixed on further versions.
Towergirls Kingdom: Conquest is a really ambitious project that has been carried out with great care and affection, and I hope that it will stay like that.
