Following the release schedule for the Leap Motion Controller and tease that Double Fine would have a game of its own for the device, more details have come out. This new title, "a music driven score challenge game" designed by folks who worked on Kinect Party, is called Dropchord.
Set for release this year initially on Leap Motion's app store Airspace (Windows and Mac), Dropchord will also be available for iOS devices. In the meantime, there will be playable builds of the game at South by Southwest this Saturday and at Double Fine's PAX East booth.
It's unclear exactly how this will play, as I've yet to come across any footage, but knowing that hands and fingers will be tracked gives me some ideas.
