Playing the Game
Explore Delfino Island and defeat enemies to collect Shine Sprites. Blast enemies with your Fludd or jump on them to defeat them. Clean up pollution with the Fludd to unlock new areas. Avoid taking damage, or your health meter will deplete; if it empties completely, you will have to restart from an earlier checkpoint. Collect coins to restore your health. Follow the on-screen objectives to progress through the game.
