Sony have put up a video walkthrough of a portion of Gravity Daze for the PlayStation Vita. You can watch it below:
Gravity Daze is set in a floating town called Hekseville. The protagonist is an amnesiac girl named Gravity Kitten (or Kat). Gravity Daze has a Gravity Change feature, which you activate by pressing the R button. After you activate it, the game goes into a zero-gravity state, and you can adjust the camera by tilting the Vita.
Once you press R again, the direction the camera is pointed in becomes the direction that gravity flows in. You can use this feature to fly or walk across walls. Another action called Gravity Kick can be used in combat.
Gravity Daze is being developed by Sony, but it looks like the game won’t make it out in time for the Vita’s launch. No release timeframe has been announced yet.
