The line spacing is way too tight (this is line-spacing: 1).
Obviously that is beneficial for ASCII-art (smaller vertical gaps), but plain text would benefit from at least 1.1 and maybe 1.2.
I am not a typographer but the cap height of this font (I think it's the cap height) appears quite large, when perhaps it would be better to have a slightly smaller cap height so the ASCII-art features would work well at line-height 1.0 without the letters feeling so vertically cramped.

Basically, slightly less-tall letters.
But as I say, not an expert.
