That would be an awsome throw back to see the characters run like SMW.
It would. Remember though, Mario, for a mushroom world person, is running pretty fast. Just look at how slow goombas and koopas move. Also, he has to pull off some pretty wicked jumps, so maybe leaning over prepares him for that, like he's prepared to put all his forward momentum into his jumps.
Gearmo, I know cleanliness is important, but for the love of all that is holy, WHY must I do it in 30 seconds???
