We normally see Mario's world from an external vantage point that doesn't exist in his.
Imagine a normal brick in our world, what we see are projections of the outside surface, but we of course can't see inside the brick, not without breaking it at least, but then you end up with a series of smaller objects that you can only see from the outside, again.
Likewise, Mario wouldn't be able to see the shapes we see because we're looking at the totality of them, the outside and the inside, all at once, because we're 3D, but they are not.
He would only be able to see the outside, which in his case are the lines making up the contours of the bricks, goombas, etc.
Probably, but there still would be distinct "points" in so far he can perceive them. We need them stretched out a bit but there's not two pixels in this game's width dimension, it's the same point stretched out in our screens, never is there more information besides one pixel than another in our screen in the horizontal axis from what I can tell.
