Google has removed popular psychological horror game Doki Doki Literature Club! from the Play Store. According to Dan Salvato, who led its development team, and publisher Serenity Forge, Google told them the visual novel was removed because it violated its Terms of Service in its depiction of sensitive themes. The game is “widely celebrated for portraying mental health in a way that meaningfully connects deeply with players around the world,” they said in their announcement. Its free version, which came out first, has been downloaded at least 30 million times, while the paid “Plus” version has had at least one million downloads. The visual novel has repeatedly made Engadget’s lists of favorite games over the years.

Doki Doki Literature Club! has the drawing style and the makings of a typical dating sim, but players find themselves confronted with serious themes, including depression and suicide, soon after starting. Its Play listing was appropriately marked as “Mature 17+,” which means that children won’t be able to download it if their devices have parental controls. In addition, the developers clearly communicate that the game tackles serious issues. “This game is not suitable for children or those who are easily disturbed” is the first line of the game. “In-game content warnings for such material can be enabled in the Settings menu at any time,” it also warns players. In settings, there’s link to a page that lists content warnings that apply to the visual novel.

We’ve asked Google for a statement on why the game was removed, and we’ll update this post when we hear back. Salvator and Serenity Forge said they’re doing everything they can to “find a path forward for getting DDLC reinstated on the Google Play Store.” They’re also looking at other methods of distribution for Android devices. At the moment, the game’s Play listing shows that it’s still not available, but it’s still out on Steam, PlayStation, Switch eshop and iOS.
