Updating my review from a 2.5 to a 3.3 score, based on the 0.3.0 version and having played through all available chapters.
+/- Renders range from good (outdoor environments), to poor (characters and some interiors). Overall passable, but not up to 2024 standards.
+++ Some good (and fluid) animations, helps the renders quite a bit. And there are a lot of them across several chapters, many of them repeatable. It's a serious value-add to the game, and could be called it's primary strength. Some good fapping material there.
+/- The "lost son comes home to mother/sisters" storyline, but with a small twist.
++ Several of the LIs have amazing figures, which saves any lost interest in the other less attractive family members. Early in the game there was only 1 good looking one, but as it progresses there are quite a few more, and they are very attractive.
-- Almost no shadowing on characters or environments. Makes things look fake and frequently 2D. This is probably due to the use/re-use of backdrops for areas, and characters overlaid on those backdrops. Helps with render time, but immensely hurts quality.
- Some models (older sister & mother) have hugely unnatural chests/butts. Clearly a developer fetish. Detracts a bit from them at first, until you see them nude and they appear more normal than when clothed.
-- Textures on models and objects can frequently be poor (whether due to resolution of source material, or settings in the renderer).
- Game could benefit from render/scene transitions, as many of them are jarring.
--- The worst part of the AVN at this point is the Grammar, Spelling, and use of words. Clearly a poorly done translation - I can't find a single sentence that isn't flawed, and it makes reading it an absolute chore. Thus the reason for the early review.
+/- Update on the grammar and spelling: only the first chapter of the game is utterly horrible at both - chapter 2/3 don't have nearly the same problem, and are much easier to read as a result. Why the dev hasn't had chapter 1 proofread/edited is beyond me, but having the game improve it's readability is a massive relief.
I'd recommend the developer spend far more time on render quality, even if it slows down production. They also need to get an Editor or Proofreader on board for English and have it Chapter 1 completely re-written. They need to re-do many renders already in the game to bring it up to standards most people would accept. Finally, they need to re-do some of the character's bodies so they aren't so garishly (and unrealistically) huge, prior to the re-renders (no longer an issue from what I can see late-game).
After progressing past Chapter 1 (if you can stand to play a few hours with horrid English translation), Chapter 2/3+ offer a much better experience, and I'd even recommend it from that point onward.
