It's been so long since I've played an update that it is difficult to remember what the early game was like (replaying from start), but it strikes me that there have been changes (don't see popups for karma score anymore for example). It's also my impression that some of the early Minami , Shelia, and Asuka events have changed slightly (probably for plot reasons if it isn't just my memory playing tricks). It seems much more obvious that the MC's innate pheromones are important: Rachel needs them to manufacture the lust perfume, Minami and Shelia seem to be affected by them before our MC gets the perfume just from sexual contact, and something had to prompt the framing of the father other than shits and giggles for the girls involved. One question that needs to be answered is just why did George invite the MC back? It almost looks like a setup to get a pheromone source back in town?
A couple of pages above there is discussion of the new content that's been added, but it will probably take me a day of dedicated gaming to get there (this is a big game after all). I'm just going to strap in and enjoy the replay with HD images and Maim Lain's walkthrough mod for the best experience.
It's a great game, that's never been an issue, but I'm going to wait for at least one more update in the near future before restarting my patreon support. I'd love to see this finished off properly, and then move on to the next project.
