Whoa, you weren't kidding when you said it was big. 9MB, 9000 by 5000 pixelsMASSIVE artwork, we can even see the Comet Observatory on the top right, so that means Rosalina is back.
Anyway, the top right just looks like some Bowser-themed Las Vegas/carnival or something, not the Comet Observatory?
I want this game... but I don't have a WiiU
