The team at Nyamyam is also looking at other Wii U ideas:
And what a lovely question and response:
NL: Do you have any ideas for future projects, which could perhaps leverage the capabilities of the Wii U hardware?
JS: I am very intrigued by the possibilities for new types of multiplayer games the Wii U could deliver. It is something I would like to think about in more depth after we have finished Tengami.
And as said, David Wise (DKC series, DKR, SFA) is on board composing the game! :D
NL: Given your backgrounds as Rare developers, does this feel like a sort of homecoming for you, being back on Nintendo hardware?
PT: Definitely. I have fond and nostalgic memories of the years I spent working on Nintendo consoles at Rare. I never imagined I would have the opportunity to work with Nintendo again so soon after starting Nyamyam. It's very exciting.
