Okay, so 48 minutes of content if you're a "true husband" however...
1) It seems to be translated, the quality screams google translate. Use DeepL, its way better. Not perfect, but magnitudes better than Google, depending on the language.
2) There is a lot of places that use "Nick" instead of whatever name the player input. Seems mostly to occur in the "new update" area rather than the early game.
3) The game is practically forcing you to do stuff with Alice. The choice is pretty much an illusion, given how much the MC comments and makes notes of Alice, to the degree if you did nothing with her, he's literally having a wet dream about her at 40 years old? What?
4) The maid/slave role play was a bit of a turnoff, that's my personal preference. It also leads me to understand though male domination is probably a thing for the future which brings me to:
5) I just noticed the future tags. With those planned tags and how Alice is basically being forced onto the player as well as his very obvious perversions to younger women, there isn't really a choice at all. It honestly feels like the game is "how much sex content do you want" and there is no reward for being a "true husband" here.
6) As someone in my 40's, I can say two things very confidently: his hair is way too silver already, like he doesn't need to look and dress like he's from a different era. Secondly, unless he was a student in his 30's, there is no way his old swimsuit will still fit him. I don't think you understand just how hard and how much effort it is to maintain your body and how drastically it changes after 35. If he hasn't put on at least 40 lbs from his student days, he's literally a scientific marvel. For real. Even if he works out all the time (he has a desk job, lol), he'd be bulky. If he isn't working out (I repeat, he has a desk job. working from home), then it's odd he has no gut. It's a game though, so whatever, but maybe don't make his hair completely silver
I guess that's all I noticed in this game/playthrough. It's probably not a game for me though, since it looks like its basically a horndog MC who is just going to be banging literally everyone and it will all work out, its basically a free sex simulator. I'm not really against that, I think its popular and a fairly popular genre for most people. I just don't like the fact there is no rewarding play and all the choices are going to come down to "what scene do I want to see with whom" and "who will I add to the sex fest" which makes it very unmeaningful.
I think it sounds harsh, but this is just a honest critque and I do wish the Dev good luck! Again, I can't emphasize this enough: if you're using a translator, use DeepL instead. Also please make sure you're using your name code and not just writing "nick" or whoever is renamed (I left the girl's names as default, so not sure if they have similar issues, but I am gonna go on a limb and say they do)
