I have seen a few people comment about how that, now that it's almost certain Felix knows about his wife and Zack, there needs to be some reaction. Yep. Agree.
However, I wanted to put my five cents in on the whole game.
CGs are still FUCKING HOT. Seriously. Very few games have scenes or graphics this good. Thumbs up. The writing is pretty damn good. How slowly Sophia is corrupted, how it happens, you could see it coming, and yet the writing for her has been great from start to finish. Amy is great too.
Zack is porn realistic, I guess. Ehh, he doesn't have as much character as Amy, Sophia or Felix.
Felix, oof. You really feel his growing confusion and disconnect, especially from the second scene in the gym and on. But he's not entirely dense, and does realize what is going on. I think his decision to not confront her is okay? but should maybe be a choice for the player. Even if doing so just leads to a early game over.
And that brings us to choices. The game had choices at first. I haven't played through the last two updates on Sophia's side - I don't want to speed through the writing, and time, time, I have no time - so correct me if I am wrong, but there haven't been any choices in a while. And those that are there don't seem to do anything. So is the creator (or plural since, again, holy shit that art) planning to go back and change that? I remember reading something about multiple paths through the game, and there's already been one Happy Ending for Felix.
I would like to see some choices that let Sophia control how hard she is corrupted. I can see the appeal of what's been going on. I always find secret sex great. But I prefer secret sex where the person being cheated on never finds out. A true cuckoo situation - the guy doesn't ever realize his children aren't his. This would include some control over Sophia's physical changes, so that Felix doesn't get a clue... outside of how loose she is LOL.
At the moment, the game plays more like a kinetic novel than a game. Sorry.
