I believe there's plans for Kari to get her own 'route' (not sure what that'll entail. There's currently no story content involving earning money, but I believe that's also planned (game is in development after all). Don't really know anything else at this time.
I'd personally love to see Unniex implement more morbid pregnancy variations to the dreams (Play Unnie's other game to know what I mean) and possibly a daytime birthing event if you manage to get her pregnant in the waking world (not jessica transformed).
