Set out with Kijino along quiet woodland paths and into caves beneath the island. The journey unfolds across more than 30 stages, accompanied by over 40 folk-inspired tracks composed to suit the scenery. The music gives the island a voice of its own.
When skeleton pirates, slimy monsters, and ghostly foes block the path, fight back with combos of punches and kicks that leave claw-like flashes in the air. Landing hits feeds the flames in Kijino's two tails, strengthening a special attack that can sweep through several enemies at once.
As the journey goes on, the island offers new ways forward. Run, jump, and dash past obstacles, swing across gaps on a grappling wire, ride minecarts along tracks that disappear into caves, and take the controls of a golem. The controls are easy to learn, and if you make a mistake, you can retry immediately from the last checkpoint.
Meet new friends along the way, and watch the story unfold through their expressions and in-game illustrations. Seek out hidden treasures and collect outfits to make Kijino's look your own. New sights and new ways to play keep you wondering what lies beyond the next bend.
Newcomers can progress at a steady pace, while experienced players can try three optional challenge settings, such as making enemy attacks fiercer or capping max HP at its starting value. There are 47 Steam achievements that encourage different ways to play, like reaching the goal without defeating any enemies.

Developer Comment
“I want to create a world where the sense of adventure you feel in a game’s very first level stays with you all the way to the end.” That idea has been at the heart of this project.
"When you first start a game, there’s that feeling: “I want to see more of this world.” To keep that feeling alive until the end, I built the forests and ruins one scene at a time and designed the stages to introduce new ways to play as the journey unfolds."
"Music is also an important part of shaping that world. While the landscapes were still taking shape, I shared them with the composer, who wrote music to suit each place."
