This game is surprisingly good.
It is still very much in the beginning, but what is there is really enjoyable.
The plot is not really original, there are several games and other works with the same or at least a similar set-up.
Old fart dies, gets reborn in his younger body or in another younger body.
Tries to get with the people he couldn't get with before, including his own family.
But it is done well here. The dialogue is mostly nice, you have the option between seducing or romancing the girls, and it's a nice collection of anime/hentai trope characters.
The girls are all a bit on the thick side and most have very large tits.
I happen to like tits, and while they are indeed ginormous, it isn't a problem for me.
There is humour, the writing is decent, the renders are fine. Nothing bad I can say about it, but it does have two minor flaws that detract a star from the rating.
For one, the grammar and spelling is abominable. I was really pulled out from my enjoyment, because of the spelling and other mistakes.
The second is more of a personal disappointment and didn't really reflect in the actual rating. You have the mother of a former friend who is a gorgeous MILF, and you have the teacher who is also fucking hot, and you CAN flirt with the teacher, but neither her nor the MILF are in the list of love interests you get stats for, which makes me think, they won't be full-blown LIs.
Now, for another positive thing I forgot, I liked how the MC has really diverging memories from what he experiences in the past.
We don't know yet whether this has any actual meaning, or whether it's just faulty human unobjective memory.
It does seem kind of weird, that he completely forgot one of his closer friends, though. Maybe there is more to that at least.
