5x5 fonts is HUGE. Minimalist OK ; small it's NOT. With such a big size of array, everybody can create very easily thousands of unique characters. Complete 3x3 & 3x4 fonts ARE minimalist, the rest is useless (or a waste of space). Good job anyway about your very first attemps with the lower case and punctuations, but try avoiding the duplicates next time, so that it can be named a FONT - since if you want to be terribly minimalist : just post 1000s of enormous, empty and identical glyphs, and we would all say : Wow ! it's space ! ;-)

PS. But your effort was appreciated. The abnormally wide and tall characters can be fixed with even more work, that's what I meant.
