Strange, the S and Z look better as the opposite of the shapes I expected them to be. 15 letters are basic shapes, 3 letters are 1x2 constructs, 6 letters are 2x2 constructs, and 2 letters are 3x3 constructs.

This is the small version

I'll make a small version cuz this is kinda too big as a pixel font and too small as a usual font lol

Font built on a dotted grid. The sort of font you might create with a geoboard.
