> 5x5 isn't enough to draw "e" properly if you also want lowercase letters to have less height than uppercase

It can be enough if you "cheat" and make use of the horizontal space. This is how I did it in my font:

I think that's the least of the properties I'd be willing to sacrifice to have a font that tiny.

I think the `e` looks better in the 'real pixels' example they gave; I find my tends to 'fill in' the space of the top part of the letter, and I suspect in the context of a longer sentence it'd be pretty easy to parse.

(but yeah, it's not quite right, and is especially jarring in the nice, clean, blown up pixels in the top example)

It definitely looks better in the second screenshot than the first, but you have to be very, very close to the screen in order to see individual pixels like that. And on low-res displays, which this sort of font might be necessary for, it's going to look somewhat different because low-res screens tend to be chosen for cheapness, and cheap screens tend to be monochrome, so none of that artistic fuzzy subpixel coloring.

Was it intended that we should fill in the word 'mind' ourselves, to prove your point???
