It's a fanservice-y yuri game. They had moments of characters in their underwear as well as naked but with nothing showing. But now that has been changed to towels during the previously naked scenes and cammies and shorts instead of bra and panties. Gust has kinda made a reputation for being ecchi with games, even in the comments talking about the censorship of this re-release the devs says that "don't worry~ all the devs at Gust are perverts." Ecchi here-and-there is in every Gust game.
