In original Mario he does have only one eye though, and it’s on the side of his face?
No, Mario has two eyes. You can see the other when you go the other way.
To have two eyes there should be some horizontal separation between them, which can't happen in 2D.
Earlier quoted context omitted.
Yeah, as someone with a lazy eye 3d honestly isn't much different than 2d.
But eye don’t really see in 2d anyway. There are plenty of tricks involved in the vision cortex based on how your head moves and how your eye scans and accommodates for its 3d field of view. It’s far more complex than just producing a 2d image for the brain to interpret.
So is that a pun, a spelling error or bad english?
I want it to be the former.
how is this 1d when there is a second dimension albeit small?
If you mean the line doesn't have a single pixel width, this is what the website explains: How is this 1D? The game is more than one pixel wide! The game width can actually be adjusted, including to a width of one pixel. That's how I prefer to play, but other people had trouble seeing what was going on. Regardless of how much you stretch it though, there is only one dimension of information, the horizontal smear is e…
Granted, I am bad at math/trigonometry/geometry etc., but in my understanding, 2D can only work from our perspective, because we're looking at it from a perfect angle.
Mario shouldn't see anything, because his viewing angle does not exist. Or is the rule about 2D that his perspective just has a width of at least more than nothing?
My lack of understanding can probably be explained with high-school material, but I can't imagine it myself.

Well, we see the world as a 2d projection BUT we (usually) have 2 eyes so we have some amount of 3d-info. Maybe mario has 2 eyes too, which would give him some amount of 2d-info. (Just like an MRI can construct a 2d slice from 1d info). So the first person game should have maybe a depth info on those pixels. What I mean, mario does not see only a line. He sees a silhouette of what lies ahead of him.

In the game Mario clearly has two eyes, side-by-side like our own. How did he evolve this feature if there is no benefit in his world?

I think it would require one eye above the other to have depth perception in his 2d world. Eyes can’t even be side-by-side as that axis doesn’t exist. Having said that, the human brain is capable of reconstructing a 3d perception with only one eye through learnt understand and interpreting the picture change over time as you move. I image it’s the same for Mario, but in 2d.

We could also describe all of them in terms of a two-dimensional plane [(0,0), (0,1), (0,2) etc.] but that would just be redundant. Just like representing the number line with a taller figure doesn't really make the abstract line any different:

Consider that any 2D image you see on your screen is just a single-pixel deep 3D image and a single-pixel 4D-protruding 4D image and so on.

Plumbing does not get any easier when you lose a dimension's worth of eyesight.
You can't even connect three houses to three utilities.
