Circle Entertainment is bringing Koi DX to the Switch eShop this week.

Released on the Wii U a while ago, Koi DX places you in the role of a lone fish which has become separated from its owner and is tasked with purifying waters polluted by mankind. Naughty mankind.

To do this, you must explore the waters for other fish and guide them to flowers of the same colour while avoiding the malevolent black fish. The game includes "memory jigsaws", new skins and alternative fish to control.

Did you check this one out on Wii U? Will you be giving it a spin on Switch?
