To be honest thats what i feel about this game.
Yeah. Just a shame, some good potential here. The graphics and aesthetic, the lighting, and ambience, is not as slick as many games which use this engine, like Eternum or Realm Invader, or especially really top notch stuff ... graphically speaking... like New Horizon, City Devil or MayFly.... but the story is sound and there is a lot here... BUT... the Adult content is just under cooked and not really well realised.
My position is if you are making and AVN, make it because the A bit matters and is important to your game. If you are adding Adult/Sexual Content/NSFW etc tags to your game, because YOU HAVE to, not because you WANT TO, because it critical to the game... then just cut that content, have it as shadows on a wall, suggestive imagery, or even just good old Fade To Black.
Sadly, whilst the scene with Claire was hot AF, almost all other scenes are meh, and not really necessary to the story. Claires one could argue, was, because perhaps crossing that line, and bonding that way, sealing the deal re the sexual and romantic energy, however taboo, between you, could be seen as critical to her revealing who she actually is and who she works for, and why she is on your side. All other adult scenes? Not really. At least not to the extent some other moment of bonding between the MC and his would be harem could not have sufficed as replacement. Kissing. Embraces. A FTB scene. Truth told, even Claire's scene could have been that way.
If the Adult element of your AVN is not CORE to your AVN, then just dump it and make it a VN.
If it is... DO NOT MAKE US GRIND for it, and do not make is fleeting... make it HARDCORE pornographic AF, lean in to it, make it delve deep in taboos, and fetishes, and really be glutton in how you gorge on making that content.
Otherwise, you wind up here, with people giving up on your game, despite the other great elements.
