All versions of the game roughly follow the
plot of the film, though different versions of the games generally omit certain parts of the film's story. The goal is to complete different levels whilst playing as the film's protagonists Nemo, Marlin or
Dory. Whilst most levels are played in a left to right side-scrolling manner, the game also continues a number of minigames and other alternate. It includes cutscenes from the movie, and each clip is based on a level, e.g. hopping through a batch of
jellyfish. Most levels have optional tasks to complete to obtain Gold Starfishes, which will allow the player to play a bonus level. The
Game Boy Advance version consists of side-scrolling adventure/puzzle stages along with several minigames interspaced across its length. Each level and minigame is based on a specific scene from the film. Collecting star rings found throughout most levels will give the player the chance to play a memory matching game at the end of each level, which upon completion will unlock an image in the game's gallery. The game does not support
saving in its Game Boy Advance version, instead opting for a password system to allow players to carry on from their last completed level, and can be also used to unlock all the images in the gallery. == Development ==
