Rhyme Rider Kerorikan is a rhythm game from the same developers as PaRappa the Rapper and Vib-Ribbon. It’s a WonderSwan exclusive, so was never released outside Japan. It’s quirky, fun, but quite difficult. It’s often recommended to English-speakers since you can enjoy the gameplay without having to read much Japanese. However, the physical cards included with the game explain the button combinations for various obstacles your character faces. I’ve added a new translation so hopefully it will be easier to enjoy this tricky game.
