Hi, thank you for your clarifications, they might be useful for some players.
However:
1. There's no "old" version, since the build hasn't been touched since 2017. This is the same version that was accepted into Steam back in the day.
2. The images are not explicit, as warned on the game page: genitalia is always off-screen and there isn't full nudity, not even censored.
3. The sex scenes are very few, and are there for the sake of the story, not being the focus of the VN at all. In fact, whoever plays this only to find sexy scenes will probably be disappointed, since they'll be forced to read 2 to 5 hours of novel before reaching any sexy stuff.
4. There are no adults involved with the protagonists. The story themes are friendship, first loves, and coming of age.
Hope this helps to decide whoever is on the fence between downloading the game or not, since I, as the author, wouldn't like readers to open the game blindly, without any warning about the content.
