Fluidity is a WiiWare 2d platformer developed by Creator/CurveStudios. Also known as [[MarketBasedTitle Hydroventure]] in PAL territories.

You are a puddle of water controlled by tilting your Wiimote. You have to clean pages of the magical book off The Influence -- bad black goo. You destroy black enemy blobs, collect Rainbow Drops and puzzle pieces and get power-ups.

Sequel called "Fluidity: Spin Cycle" was announced for Nintendo3DS, coming to eShop December 2012.

* {{Metroidvania}}: big interconnected world where you have to gather power-ups to advance.
* PinkGirlBlueBoy: your character in ''Spin Cycle'' is a blue water drop. Rainbow Drops you save are girly looking and pinkish.
