The First 15 Minutes of Entwined (Vita)

Copied from MobyGames:Entwined is a rhythm game, based on the Chinese ancient myth, where two souls are in love but can’t be together. The player guides both souls (a bird and a fish) simultaneously by using left and right analog stick in order to bring them together over the course of nine lifetimes. The souls are rushing through a closed circular tunnel, collecting colored spheres along the way. In some moments of the game lovers closer to each other and transform into a magnificent soaring dragon. At this point the player can move freely in the open space, creating kinetic sculptures, which are bounded by the track left behind in the air.
