I can't put my finger on it but I don't find this enjoyable to read at all.. so I don't know much about readability claims here. Maybe I'm an outlier.
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.
