Brothel King is another take on Sim Brothel and gets some inspiration from other games, such as Slave maker. It's made with Ren'py, my objectives being to make a fun game with a clean UI, good art and a full back story (which isn't yet developed).
The update corrects some bugs, adds a cool new UI feature in the city, as well as the 'packstate' feature that Chris12 made.
Some core features have been tweaked (including the way the game gets pictures and how brothels are generated). This shouldn't break saved games, but it is likely to have bugs.
