You know, now that I think about it, since the dev has stated that there will not be a harem, maybe a feature [or mod] that allows you to turn certain relationships on or off would be a good idea. Several games do that, including most if not all of Mr. Dots' games. This means that you can explore all content and then switch to a preferred woman to end with without ending up with a pretty bad conclusion.
That, combined with the suggestion I made before about being able to adjust stats and whatnot, would add a level of functionality to the game that I think would increase the enjoyment of the game.
