From the makers of ace attorney. They just released a flash demo, so I'd take a chance to look into it if you haven't already.

Unlike AA though, this demo is actually playable since it's a really visual game. This isn't a text adventure. You play as a spirit who has to jump into random objects in the world and "trick" them into doing things to prevent a murder. Also, smoothest animations on the DS.
