Coded was announced at the Tokyo Game show on September 20, 2007. Coded will be directed by Tetsuya Nomura and co-directed by Hajime Tabata. It's the first collaboration between Square Enix and the Disney Internet Group. Nomura had mentioned earlier this year [2007] that he wanted to do a spin-off KH game on a mobile platform, and that he wanted it to play a little differently than the other titles. Coded is being developed with 3D and 2D graphics to have the game available on a range of cellphones.

Coded will be a puzzle game with some action mixed in along the way. The action parts will be similar the the previous RPG style with the same basic interface. Backgrounds will be 3D and characters 2D. The original trailer showed Sora in dungeons with floating red and black locks. Battling features "debugging" mode to remove those blocks. Those blocks are also used to solve puzzles or reach higher ground.

Plot;Coded is set after the events of KH2. Jiminy Cricket goes back to Disney Castle to organize the records in his journal. He finds a message he did not write. "We must return to free them from their torment." To investigate the message, Mickey digitizes the contents of the journal, awakening a digital Sora on Destiny Islands.

Characters;Coded will feature numerous Disney characters. Confirmed characters: King Mickey, Pluto, Jiminy Cricket, virtual Sora, Donald, Goofy, and the Heartless. Figures, those damned heartless. Anyway, the virtual Sora is in the original Sora's clothing from the first game, because he is created from data from Jiminy's earlier entries. The characters reffered to as "them" in the message left in Jiminy's journal refers to the main atagonists of the game, which is not revealed quite yet.
