Honestly, it’s an excellent game up to a certain point, but there are several aspects that I find important to mention, as they personally felt annoying or poorly executed:
1. Exaggerated character designs:
I understand that some people enjoy a more fantastical style or exaggerated features, but in this case, it becomes absurd. For example, Bella has completely disproportionate body features. Sure, one could argue that she’s an adult and that this represents physical maturity, but the level of exaggeration is ridiculous and breaks any sense of realism.
While Bella and Nora seem to be walking goddesses of Italian and Norwegian descent, this isn't comic level of proportions as seen by many other games on this site. (e.g. Nora's lab coat is certainly big in the torso area, but there are plenty of fat science profs.) It certainly didn't take me out of the story, but I see what you're saying. The rendering of textures on their bodies (even Jill), do, however (e.g. their winter jackets during the skiing stick to them like glue.)
2. Repetitive and tedious pacing:
There comes a point where moving from place to place, talking to different characters, or completing certain tasks becomes exhausting. A clear example is the Halloween event — having to talk to every single person at the party is more annoying than enjoyable.
Many have stated the walkabout scenes, as well as the optional mini-games (though skippable), are too long, too convoluted, and take up so much time, and are boring. This is 90% true. There is no reason at this point for DPC to keep doing these...but he can't
$$$$$ help himself. Also, the party planning is a core mini-game for some reason...like Being a DIK involves...being the DIK's party planner...
3. Visual inconsistency:
In some chapters, it feels like certain characters change their appearance noticeably. This creates confusion, as if the art style or model of the character was altered without a clear reason.
Could you be more specific? Art style? The quality of the renders have upgraded from the first season, sure, but I'm not sure if the art style has changed? Maybe better lighting? But for static model meshes, I think this is a good thing, as characters shouldn't be wearing the same outfits or have the exact same hair styles in certain cases. Of course, the time frame is around half a year going into January, so clothing, hair, shoes, winter hats, etc., should be different. The way the MC gets a haircut is a nice story touch.
However, I think Sage is a good example of what you mean, where her hair style of having uneven short bangs, and then back to a full head of long hair, and back again, doesn't make sense.
4. Flat story:
At various moments, the plot feels stagnant and lacks depth. The characters don’t seem to develop or face meaningful conflicts that lead to real change.
What plot?
And what drama you were on with a particular girl could have Been Destroyed ™

5. Unnecessary sex scenes:
It feels like almost every female character ends up wanting the main character. I understand the game is set in a university and aims to reflect a youthful environment, but the excessive amount of these scenes makes the story less engaging and less believable.
I would argue there are too many characters, and DPC wants too many options, bloating this Milk Machine with filler. So while I do appreciate the high quality of intimate scenes and their number, for characters we can focus on,
there are too many optional SGs that shouldn't exist with them, all for the Others/DIK route. I think DPC has forgotten to put the Pink Rose girls in rotation, even if they're still in the narrative (so what was the point? Sandy is hot for MC, but can never get with him again? And he just keeps introducing more options each chapter...) Even if characters like Tara and
are compelling to some, they're coming in too late, and now have to play catchup. Which means
even more future scenes.
