Hmm yeah I didn't even think about it you know. I just assumed it was as that's the type of game it is but it seems like it's local only. I guess you can scrub my comment about 3DS friend codes.

If anyone wants to play on the Wii U then send me a pm though. I am disappointed to hear it's not online but I should have investigated a bit further before buying it. I'll still play it for gathering and helping the missus when she wants the Wii U though so I'm not devastated.

Maybe someone can try testing 3DS tunneling....
