KOI

KOI is an adventure game in which the player takes control over a lone koi fish on a journey to return home. Explore 8 artfully rendered levels, alternating from the bright unexplored world found above the waters to the dark, ominous deep sea located beneath the surface. Gameplay revolves around exploration, solving puzzles and completing mini-games while avoiding the dangerous Black Fish and other hazards. KOI is the game that asks players a simple question: Can you bring purity to a lotus pond, and in so doing, bring happiness and peace to your mind?
