The First 15 Minutes of Giana Sisters: Twisted Dreams (Wii U)

Copied from MobyGames:

Giana Sisters: Twisted Dreams is a sequel to the 2009 re-imagining Giana Sisters DS. Giana and her sister Maria were in bed when a warp gate appeared, in which Maria disappeared. Before the gate closes, Giana jumps through it to rescue her sister. There, she finds herself in a dream world full of foes.

In this side-scroller 2.5D platformer Giana can swim, jump, kill enemies by jumping on their heads or 'twist' the dream, and collect gems to unlock the next levels. When Giana twists, the entire dream world is transformed. In the Nightmare world, Cute Giana is peaceful, mocking the nightmare which once frightened her when she was a child, and with peaceful music in the background. Cute Giana can twirl, spin in the air, and fall very slowly. In the fairy dream world Punk Giana is upset and the soundtrack is turned into metal music arrangements. Punk Giana can bash, reach high passages, destroy weak obstacles and kill enemies.
