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.
Frankly, nothing about Sayonara Umihara Kawase makes it a welcoming experience. The controls might be tight, but a platformer where the physics are a constant battle, and the levels restart so slowly, make for an extremely aggravating adventure. While the mechanics might make it work better at a puzzle platformer, this still demands cat-like reflexes...
If Steam is the only resource to experience this game, it's still worth checking out, but those who own a PS Vita or PS TV should consider that the definitive platform instead.
