First off: Adventures of Pip, a puzzle platformer about a shape-shifting pixel. And it even has a skeleton queen. (May)
Octodad gets ported to the WiiU. No word on exclusive features. (Summer)
Mutant Mudds gets Super Challenge(ing), will be cross-buy between Wii U and 3DS (didn’t even knew Nintendo does this) and if you already own the previous version of the game, you get a loyalty discount. (June)
Don’t Starve also gets a port to the Wii U, offering exclusive gamepad features (Map and fast access to your inventory). Not sold? Then how about the fact, that every purchase gets a second copy that can be gifted to a friend? (May)
