A Kickstarter campaign ran through September 6, 2026, ahead of the Steam release. The demo was released during Steam Next Fest in June 2026, covering roughly the first six days of the cycle, and the demo plus the campaign produced solid interest - the game passed 100,000 wishlists in three days after the theme song was revealed.
A real-world Shibuya event ran from August 21 to 26, 2026 at RAYARD MIYASHITA PARK, and was extended through August 26. The theme song "Oshi Oshi... Kane Kane..." reached over 900,000 views on its MV, with the Vocaloid version passing 800,000 on Bilibili - unusually strong performance for a game with a 27% positive review score, which is worth noting as a signal about where its audience actually is.
The developer states plainly that the game does not rely on demanding 3D graphics processing and is designed to run across a wide range of PC environments - which is why the 4 GB RAM requirement is genuinely low. It is a text and pixel game with a heavy audio layer, not a graphics showcase.
The store page flags that the game uses close, detailed environmental audio to create the feeling of sound pressing in from all around, and recommends headphones or earbuds. This is the one system requirement that is not optional in practice - the game is designed around directional sound.
The game carries content warnings for psychological horror, violence and blood, and self-harm and suicide references. Jump scares are used sparingly by design.
A DLC entry (Steam app 4793590) is listed against the title on the store, though its contents and price have not been publicly detailed in the sources available here - and there is a separate Chinese-region publishing arrangement through CIRCLE LINE GAMES to account for. There are no console announcements, and the game is Windows-only.
