Kingdom Heart 3D has been available for purchase since late March. For the holdouts, Square Enix announced today plans for a demo, to be released through the Nintendo e-Shop on May 2.
The demo will let you control Sora in an area of the game set in Traverse Town. You'll be able to make use of Wonder Nyan, Neko Cat and Kuma Panda as your Dream Eater party.
The demo requires 90 megabytes of space and can be played 15 times.
