Just discovered a funny error in version 0.16. Once a girl have worked in the brothel, you can keep spying on her, despite she isn't working there anymore.

That said. This game has an extreme level of grinding. To get a girl to sex level 10 you probably need to fuck her over 100 times, and there are 10 different kind of sex, each with 10 levels. That mean's repeated sex scenes over 1000 times with each girl to get them to level 10. This game will be in my trash bin LONG before that happens, as grinding stats is something that REALLY annoys me. It's a little sad, because for once I found a game with BDSM, rape and forced work in a brothel, without raw physical violence. All things that is high on my enjoyment list.
