Good question, but the problem is related to very high grind that the game has. Using cheats is a big improvement for you to reduce wasting your time in this game, but there are also other things that have not been reported.
The management of this game is not very good, I mean it's regular, not bad but not very good either. There are people who have different tastes, such as the girls' arts, there are people who like and others who don't, I personally don't think it's very good and not too bad either, but I think the arts should be a little better, I'll cite an example, the art of Minami, look at the difference between this art and this other 1* Angela 2* Minami you will see that there is a big difference, of course it varies on what kind of tastes people have.
<Angela (Excellent) - Minami (Horrible)>
The good thing about this game is that it's a sandbox dating sim, where you can relate to several girls, the girls are jealous, you can dominate them or submit them (submit there is not enough content, just Sasha and Aletta), get them pregnant, there are climates such as summer, winter, autumn.... (but girls when it's winter they don't wear winter clothes, or when they're summer they don't wear summer clothes...) well, is a fun game to play.
The bad thing is the bugs that sometimes happen for example, there was a bug with Emma, I gave up playing at the time because of that, the grind that thanks to cheats you can play with god mode, some perks you feel are not effective, there is no sleepsex (this is preferred, let's say it's not good or bad), and among others that you will notice or not when playing.
Because the game has a three stars rating, there won't be a game that will please everyone, but little things in the game could improve. The sex scenes are also some good and some bad and there isn't a wide variety of positions or interactions with other scenarios, so maybe that's why you work hard and get rewarded with little.
