Quoting Nintendo Life's review:
"Fluidity is easily one of the more original games on WiiWare and comes with hours of replay value, a slick physics engine and spot on controls. The huge 2D maps are full of secret areas and unlockable extras, and the pacing of the game keeps the action from ever becoming too repetitive or dull. What starts off as a simple tilting affair soon evolves into some of the most refined gameplay mechanics ever slapped onto the Wii Remote. From simply directing the flow of a stream of water you'll soon be blasting through doors as a block of ice, launching off spirngboards and zapping enemies with bolts of lighting from a raincloud. Fluidity may come with a steep asking price, but it's an experience that shouldn't be missed."
