TamagawaSoft has announced that the 2D action platformer "Isekai Island: Journey of Ruins and Tails" will launch on PC via Steam on January 19, 2027, priced at $17.99 or 2,250 JPY. A Nintendo Switch version is planned for a later release.
Players take on the role of Kijino, a two-tailed cat demon from Japanese folklore, traversing ancient ruins reclaimed by forests, quiet woodland paths, and underground island caves. The game features over 30 levels and includes more than 40 folk-style music tracks composed to match the scenery of different areas.
In addition to running, jumping, and dashing, players can use a grappling hook to cross gaps, ride mine carts deep into caves, and control golems. After a mistake, characters can instantly retry from the nearest checkpoint. Along the journey, players can meet new companions, uncover the story through character expressions and in-game illustrations, while searching for hidden treasures and collecting costumes.
The game features three optional challenge conditions, including enhanced enemy attacks or capping maximum health at its initial level, and offers 47 Steam achievements. The Supporter Pack, released on the same day as the base game, includes 43 original soundtrack tracks, a digital art book with 184 images, and an extra costume set.
