'Journey So Far and Appreciation' - A Message from Producer Kazuto Sakajiri

The demo released during the Steam Next Fest in June surpassed 270,000 downloads, and received extensive feedback through reviews and surveys. This Early Access build reflects these voices, featuring UI improvements and tutorial adjustments to enhance gameplay experience.

We sincerely thank everyone who supported us on Kickstarter and those who support the demo version.

Currently, Ratatan offers a unique action experience centered around rhythm and strategy, featuring multiple worlds, companion characters, online multiplayer for up to four players, and random elements that change with each run.

Future updates are planned, including the "Super Fever Skills" and Ratatan upgrades by the end of October, and new scenarios such as the Dark Ratatan Battles in December. Additionally, new worlds and major boss battles are expected in Spring 2026. You can find more details in the revealed roadmap.

Ratatan is a game that will grow with our players. We encourage you to share your honest opinions through Steam reviews and feedback forms to help shape the future of Ratatan.
