“My musical composition was inspired by the keyword ‘Ratatan’. In short, I set out with the intention of ‘creating music that would allow everyone playing to journey together in a happy mood’, and I poured my heart and soul into transporting you all into the world of Ratatan. I hope you can feel this dedication at every level! Welcome to the Ratatan theme park— let’s sing, dance and enjoy ourselves to the fullest extent.” 

 

‘I’d like to express my sincere gratitude to the players who backed us on Kickstarter, as well as to the friends who have supported us right from the Early Access stage. It is thanks to your support that we’ve been able to reach this day of official release. We’ve crafted Ratatan as a brand-new title featuring a unique world, characters, and gameplay. Whether you’re a fan of "Patapon” or discovering this game for the first time, we hope you’ll approach it with the excitement of encountering something new and experience the unique fun that Ratatan has to offer.
