I remember there was a porn movie made back in the mid-2000s called "Pirates XXX". It had the biggest budget of any porn movie and actually built proper sets, had fighting action scenes, and at least tried to have a proper narrative. It also has a shit ton of sex because, at the end of the day, it's a porn movie.
This game might have a high production value and a decently written story with fairly well developed characters, but at the end of the day, it is a porn game, because when you it strip it all back to it's basic function, it's purpose is to titilate people with sex scenes.
DPC might have the ambition to elevate the level of VNs/games with BaDIK or to simply produce something they consider higher level than all the rest, but so too did the Pirates movie producers hope to elevate the porn movie industry, so just because they may have high ambitions doesn't mean that this isn't still just a porn game at its heart.
