This is everything I hope for in an AVN. Call me a freak but I have a preference in fetish and this hits perfectly. No straight up banging all the time or endless sex scenes; bonding and building with the LI of your choice.
Story is really interesting as well, have yet to hit the "dark turn" but am a big fan of anything "superhero-y" or "supernatural" and so far this doesn't disappoint.
I'm not personally complaining because she is my LI but I did not see a way out of romancing a certain close someone, maybe that could throw some people off? At the same time when an AVN's description's first line is "You and your sister..." it already tells you all you need to know.
AMAZING work Syko134 and I'd be super excited and am hopeful that you remain in this realm of fetish (you know what I mean ;)).
LOVE THIS GAME.
EDIT: Also, the anime style is really good; the animations are extremely smooth and it is just easy to get attached to characters (even the ones you choose not to romance!)
EDIT2: Named my "Iris" "Sophie" after one of my favourite older AVN's "Crusoe Had It Easy".
