Umihara Kawase is an unusual platformer featuring a girl who finds herself trapped in a strange dream world filled with walking fish. In this bizarre place, she wields a fishing line that doubles as a grappling hook, allowing her to swing and abseil between platforms with ease.
The game's standout feature is its realistic physics system, which enables Kawase to perform various stunts using the length and elasticity of her rope. With almost 50 levels to explore, each with multiple exits, players can choose their own path through the game without having to complete every field in order. Additionally, the game allows for recording and saving of high scores, allowing players to relive and improve on their performances.
