I still say its a mistake to have TWO protagonists who interact in this way. I actually can't think of ANY AVN games where the narrative is improved/enhanced by having this. But I can think of multiple examples where it is hindered. I get the appeal, you look at a game like, Detroit:Become Human (PLAY IT NOW!!!!!) where the story unfolds through multiple perspectives, and it just works so well. But keep in mind, that they almost never repeat a scene from another character's perspective (a trap many games/shows fall into, but it's always boring), and the POV characters actually don't have much interaction with each other at all, and its mostly relegated to the story's climax (hehe, climax) and they separate again soon after.
Contrast with ORS where the characters constantly repeat scenes from two perspectives, and frequently interact with one another. Which, IMO, actually makes me feel like the worst of both worlds. I'm in the driver's seat for both of them, so I'm... dating myself? And giving me more context actually makes the story less interesting. A great artist once said 'art is not about what you see, but what you make others see' and giving us every detail of a story, every angle of a scene keeps us from imagining things, it prevents our imaginations from filling in the blanks, which is often exactly what makes a piece of art so captivating.
I would play a game about Lena. Or one about Ian. But playing as both actually makes me less interesting in either. And sadly it seems like this creates a lot more work for the Dev, without much reward. I'm not even sure there is a better way to accomplish what Eva is setting out to do either, the concept might never survive the execution.
