Downloadable on Wii U's eShop. This surpasses the demo from the Wii U display from two months ago. You guys have to check it out.
The two stages, Teensie Trouble and Castle Rock, have been modified a bit, a stage called Toad Story is included, the demo supports five players, and Murphy is playable optionly through the Wii U Game Pad in all three demo stages, including Castle Rock. If you prefer not to play as Murphy, five players can play together as Rayman, Globox (in a chain mail reskin), Barbara, and the two Teensie.
