The game features seven worlds with puzzles and enemies. The Wii Remote is utilized to control Dewy and his surroundings. The remote is held horizontally and tilted to move Dewy around the screen, similar to Mercury Meltdown Revolution. The D-pad can be used to either heat or cool down the environment, causing changes in Dewy's state. Heating the environment will cause him to turn into a cloud of steam and allow him to strike enemies with bolts of lightning. Cooling the environment will cause Dewy to turn into ice and freeze his surroundings. The Wii remote can also be moved in a fanning motion to create gusts of wind or side to side in order to create earthquakes.
Part of the plot of the game involves rescuing Dewy's Eau friends. For the first six worlds Dewy can find 100 in each of the four missions of each world, bring them to a total of 2400 through the game, and must battle a boss in the fifth one. After completing a mission, a grade is awarded to the player regarding not only how fast it was accomplished, but also how many Eau were rescued.
