I think this is on point but uncharitable... I think it's better to look at the problems with ORS in artistic terms rather than through the lens of Eva cynically chasing patrons.
The idea of two protagonists whose relationship expands and contracts based upon decisions they make with regards to each other and with regards to the people around them is a really interesting one but it was always *very* ambitious for a porn game.
I can imagine a French film director doing something amazing with the idea of two people feeling a genuine connection only to wind up messing it up because they can't break with old habits, old influences, or stop looking over the horizon for the next chance at a truly world-class threesome. The problem is that this isn't the type of story that porn games tend to tell... most porn games are either escapist fantasies with male MCs or they're weird corruption fantasies with female MCs. GGGB was a world-class example of the latter but I think Eva wanted to write more and you can sense that ambition in the fact that so many of the endings in GGGB are really fucked-up and borderline depressing when you look beyond the fact that the protagonist is having a grand old time as far as orgasms are concerned.
There is a sense in which ORS is an NTR game as the emotional dynamics are a lot closer to those of the better-written NTR games (like Misfits) than your typical escapist fantasy. NTR games often have this quite interesting dynamic where you start out trying to manipulate your GF into cheating on you so that you can fuck other people guilt-free only for it to drift slowly into 'I am perverting my GF because it turns me on to see her surrender completely to her desires' and I think that ORS taps into some of those dynamics without really engaging or wanting to be an NTR game.
Where I think OP's critique is really on point is the fact that, as written, ORS is more like two games with occasional crossovers than a game about a couple. Reading this thread, a lot of people approach the game by leaning into the MCs alternate relationships and I think that reflects Eva's struggles keeping the game centred upon the couple. To be honest, I don't get the impression that Lena and Ian are all that into each other as neither of them seem to think about each other when they're apart and nobody at any point goes 'Oooooh... maybe I shouldn't try and fuck their best friend'
With regards to the criticisms that Ian's love interests are better than Lena's: I think that's true of GGGB too... in that game, there's a nice artist and your high school boyfriend (who you wind up believing is dead) and every other dude is an abusive, manipulative, degenerate prick. I think unsympathetic-but-hot characters are Eva's calling card.
