First of all this game has potential, the writing is good, the scenes are titillating and although the green demon is annoying as hell the female and male protagonists are very good. The problem is there is not a lot of stuff to do.
During the day you can send Jack either on training (which after 4 or 5 scenes does nothing) or clear the cemetery (which gives a scene at the end of the day) but except from that there is nothing to do except make money, would be nice to have a way to interact with Jack either through training or her hunting through the cemetery. Also would be nice to send her to various errands for more corruption.
Otherwise nice game but needs a lot more work and if it would take 3 years to get here then i expect to be either abandoned in a few months or be abruptly finished in a few versions.
