Heavy spoilers ahead and opinions that don't make a difference...
As a long-time player and supporter, there are a few things on my mind about the direction this VN has taken.
It is great to see that his skills as a 3D artist have increased significantly. They were always pretty good, but they just get better each time. The sex scene animations are top-notch. However, the other animations...I often find myself asking, why is there an animation here? Is it for dramatic crescendo? They take a long time to create and work well when they are used sparingly to increase emotion or add an exclamation point to great sex scenes. It just seems to be sometimes random, unnecessary, and occasionally distracting and annoying (same in SG).
The changes to the characters... I think this has been beat up a lot here, on Discord, and on Patreon. There are some really great changes. Details that truly add to the beauty. But then there are some gigantic misses. The MC is way too swollen. Katie loses a lot of that girlish charm. And the lip piercings...absolutely hate them. Leia (the daughter) looks years older than Helen (the mother). Miru appears much less Japanese—still very cute and sexy, but just...something's missing. And all the breasts must have been grown using hormones! Shit, they're huge on every character!
Speaking of Miru, I love the story Ocean created for Miru! The loving nympho girlfriend who would take a bullet for her man. A sexy playfulness in their relationship and it carries through to the greater story. Every scene with her in it (and there are a lot) adds to a wonderful, rich portrayal of her character. But the buildup of Katie and Leia is severely lacking compared to earlier versions of the story. I do not feel the angst and heartache that Katie felt not being chosen. Or the longing Leia has had for her twin and true love. Instead, we get a weak embarrassing moment of Katie and the MC not recognizing each other but being attracted to each other when they first meet. And then some back-and-forth sibling rivalry. And Leia's no longer the sister who just wants to be with her brother (in every way); she's just angry and dismissive.
I guess there are a lot of positive changes and just as many negative losses in my view. Even though the relationship with Miru carries the entire VN and adds playful comedy, heartwarming romance, and steamy sex scenes. Yet overall, the story seems diluted and weak.
Anyway, just one guy's opinion.
