Fluidity: Spin Cycle (also known as Hydroventure: Spin Cycle) is a Physics-based Puzzle video game created by Curve Studios and published by Nintendo. The game acts as the playable sequel to Fluidity, where the player controls a small body of water that can be used in different stages of matter to advance through the levels of the game. Like the previous title, the game mixes a 2D Puzzle gameplay with platform elements. The plot revolves around the protagonist and his journey into an encyclopedia to rescue the Rainbow Spirits from a malicious ink-like substance and the scientist known as Goop. The game lets the player run, jump, as well as transform the protagonist (Eddy) into either a cloud of vapour that can float freely, or a block of ice that can weigh down switches, smash barriers, and can cling to objects. There are several levels, and each level comes with the unique difficulty setting. The player can navigate the environment from a side-scroll perspective, solve tricky puzzles to score the best points and can use to unlock further stages. Fluidity: Spin Cycle is an addictive game to play and enjoy.
