Umihara Kawase is a series of platform games, starring a nineteen-year-old Japanese school girl (Kawase Umihara), who has somehow become lost in a world of mutated salt-water and fresh-water creatures. The Umihara Kawase games' main distinction are their tranquil fish and bird infested worlds and the rope physics, which defines the gameplay. This is the third game of the series.
