I think I just realized something.
I have never liked the way Mario runs in this new game (he leans back and his arms flail everywhere) but based on that video, that's actually his walk. The player actually starts running when they grab the star, and it looks quite a bit better. He's leaning forward so his balance is more level.
I'm nitpicking I know, but I was glad to see that. I barely ever walk in a Mario game
Can't wait for this game.
