Here is how you can
very easily do your own research and answer these questions, like most people do if they are unsure whether to invest time in a specific game:
- Start by going to the first post of the first page of this thread. It has a date (in 2020) and a release date (in 2025). Divide the difference between these two dates by the number of releases, which you can find by opening the Changelog spoiler and counting the releases. That tells you the average time between releases. (Also look at the last few pages of discussion and check for complaints about recent long time between releases or small release sizes.)
- Open the "Genre" spoiler to see the tags that apply to this game. (Yes, it's a misnomer, but this misnomer is a standard on this site.)
- Look at the example pictures to get an idea of style and quality. This particular game also has a short video trailer in the "Animation Trailer" spoiler.
- The average star rating and the number of third-party contributions (translations, mods) can give you an idea of how popular this game is. If you click on the "Reviews" tab, you can read the latest reviews, which also tends to be very instructive.
- The release history and the download size can give you an idea of how much material there is.
If this doesn't answer your questions, it makes sense to ask whatever is still unclear in the forum.
As to the story: That's usually explained under Overview, but in this case there is very little detail to avoid spoiling things for people who want to be surprised. So I will put my short summary into a spoiler:
It's a science fiction time travel story ('ripples' in the time space continuum or something like that). The main character has sex with a number of women, then accidentally travels back in time where he again has sex with a number of women, some of whom may be identical with or daughters of the previously mentioned women. That's essentially where the plot is right now. This works well as a set-up for unintentional incest or similar things, which was probably part of the original plan. But due to Patreon rules the story now gives this a wide berth in a way that can probably not be 'corrected' by an incest mod. Perhaps the beginning of the story would have needed some adaptations to account for this change in direction, but I may be wrong, and I think so far that hasn't happened.
