Yeah, too soon maybe a bit of an overstatement considering that the game takes so many chapters until we find her. But, what I trying to say is that it too soon considering story-wise, I mean if I'm not misunderstanding the point of simulation is serve the purpose of the MC longing for his sister, I just think that if we still don't found her yet or maybe she really lost her memories it would be good to the story and it'll make the simulation plot to be more meaningful and maybe we'll have some tearjerker scenes LOL
But, that's it. I just think it would be good IMO. I don't think the story is bad, especially for adult game standards, I can see the dev put a lot of effort into the plot and story, I just really love the simulation plot and thought it got a lot of potentials. But, perhaps later in the story, it would be something more surprised and better than what I thought
