Anno meets Darkest Dungeon, but NSFW. Get the patch from the official Discord, nothing comes even close in variety.

Have played the previous game of this developer (Ero Dungeons) and was very satisfied with that as well.

Long time fan of the Dev and another great game.

City Builder, Exploration, and Monster Girls, what could be better?

For clarity, I have played and supported this game a lot through Patreon. This is a NSFW game, but you will need to install a patch to gain access to that stuff. That is found on MadoWorks Discord Chanel.

Game doesn't look the most appealing, but definitely makes up for it with how complex it is.
The battles are like a kinky version of Darkest Dungeon with a lot more items, classes and customizations. With the added bonus on building and managing a whole town.
There isn't a way to "lose" the game, but they do set you back some bit if you fail at something. So it's best to
learn on those failures and explore what the game has to offer to come out with new ways to play.
This game can easily get you many hundreds of hours when you get a handle on things.
