While creating this font, I had 2 tasks:
1. The font must be a minimum size
2. The font should be visually understandable

In the end, I came to the conclusion that 3x3 pixels is what I need.
Unlike some other fonts, I have a true size of 3x3, not a pseudo, sacrificing the classical appearance of some letters and numbers.

In some programs ("Notepad" for example) there is no possibility to adjust the line spacing, so you will have to skip the line so that it does not merge with the previous one...

I hope you will enjoy ;)
