Sorry that no-one ever responded to you. This game was incredibly unique, very rarely, do adult games more or less lean on the arpg element. There is speculation that Beauty And Violence: Valkyries is made by the same people, and that the game that was put on hold to make this one. (Succubus) might be similar, at least in theme, or (Carnal instinct). But typically, it feels as though these games are never finished and hidden behind an infinite paywall. So if you happen to be an aspiring game dev, you know what to make.
