Ratatan News

If we're being honest with ourselves, the original PSP was a sort of Proto-Switch too, no? As in it was home to a lot of odd, smaller-scope games that not many other platforms might have featured outside of Nintendo's earlier handhelds. Patapon was one such tiny oddity, one of the most charming games on the platform, if not to ever outright exist. It did go on to get a couple of sequels, but the series (outside of an upcoming remaster of the first two) is sort of dead. Luckily, Ratatan, a spiritual successor from Patapon's creator is here to satisfy your tiny-guy-chanting-to-music needs with a newly revealed release date!

Hello! This is Sakajiri, the producer of Ratatan.
Today, we’ll be unveiling our latest Ratatan trailer during Day of the Devs!
Not only that, but we’re also happy to announce that the Early Access version of the game is scheduled to launch on Steam on July 25, 2025.

Ratatan began with the support of our Kickstarter backers, and has been developed by a small and passionate indie team.
The journey hasn’t been easy, with a ton of challenges along the way, but thanks to the feedback we received through our closed alpha and beta tests, especially from our backers, we’ve finally reached a stage where we can bring the game to a wider audience!

We’ve chosen to release Ratatan into Early Access because we want to involve even more players in shaping the final game.
We believe that gathering broad feedback is essential to help us improve the stability of online multiplayer, fine-tune game balance and difficulty, and enhance overall usability—including controls, flow, and playability.

The Early Access version will feature all of the game’s worlds and bosses, all eight playable Ratatans, and many additional features not included in the demo.
We also plan to continue adding new content and functionality during the Early Access period.
A detailed roadmap is currently in the works, and we aim to share it around the end of July.

While Ratatan inherits the spirit of Patapon, it is a completely original title designed to deliver a new kind of experience.
As a game created by Hiroyuki Kotani, there is deep respect for the Patapon legacy, but we want Ratatan to stand on its own—as a fresh and modern take on rhythm and strategy.
To those expecting a direct sequel to Patapon, some elements may differ from what you anticipate, but we hope to offer something truly unique, built around community engagement and continuous evolution.

As we move into Early Access, we’re more committed than ever to listening closely to your voices and shaping Ratatan together with you.
Please share your honest feedback and suggestions, because we’re excited to keep improving the game with your support.
