Yeah, that's the biggest letdown of this game. And I can't even say I really understand it, because, let's face it, compared to an ordinary vn, the amount of graphics the author has to create is miniscule.
There's SOME amount of variation, not always just a few changed lines of text, but it is extremely limited.
I mean, I get it, if you don't like the subject matter, you don't play the game, that's fair.
Still, I think the game could massively benefit from having actual variety.
A mostly faithful route where things never escalate beyond playful playing around one one side, an actual ntr route where the player can consistently oppose any sort of sharing that may or may not - depending on some choices - lead to infidelity.
Such things would, in my opinion, massively boost the game's appeal, because you could compare the different "versions" of Laura. As it stands, it's for all effects and purposes very close to a kinetic novel.
But yeah, maybe the author will think about adding some variety after finishing the plotline, wherever it's supposed to go.
