This game is really cool, to me this game along with the previous version and the original game really stood out. I felt like it was a very interesting story. I got to give you credit for taking the most messed up ending and continuing it though I find it odd that in the previous version the protagonist is apologetic while in this one he is also angry. There is just something really tragic and beautiful about this overall story, it evokes so many emotions. I didn't like that there was just three endings and was hoping there was a "redemption" ending as I am curious to see what that would be like.
In terms of the visuals, it is a big upgrade from the previous version. The change I am kind of on the fence on is the addition of the imaginary characters but I kind of understand the meaning behind them and in a way adds to the tragedy especially with the "fatalism" ending.
I think that there needs to be some better English translation of the script though and changes here and there as it occasionally makes no sense. I am not sure what sort of route you are going for a possible "redemption" route but one idea that I had either he does like the previous version and lets her go in the "Robinson" ending and then someone else comes along or some sort of threat emerges and he sacrifices himself to protect her. Just some ideas for you lol. I just think the concept of redemption is a tricky thing and it seems to me the primary goal of the story. I like to think that Asuna is not just some random figment of Jack's imagination but maybe something he saw somewhere in a magazine that washed ashore, would be interesting to see the real Asuna wash ashore and Jack have another chance at redemption. Regardless where this story goes, I would like to see where you guys take this story. Best wishes.
