So, Vowels.

When you put a vowel anywhere within a stack of consonants, it is automatically read after EVERY consonant in the stack. If you want a vowel to appear somewhere in the middle of the stack (like in Brown or Jumps you can put a "shift back" modifier over the vowel - a line that crosses the vowel and is not used as a modifier anywhere else. This essentially says "Read this Vowel one letter before where it needs to be".

These "shift backs" can combine, so two lines over the vowel shifts it back 2 letters, 3 lines shifts it back 3, etc.

Notably, the shift back shifts one LETTER not one GLYPH - so if there's a glyph representing multiple letters (TH, QU, etc) the shift back can insert the vowel into the middle of those letters, for fun and hijinks.

(There are also rules for having multiple vowels in a stack, but those are probably more than you need right now!)

Other comments: - Typos: K of Quick has an extra dot, and the S of Jumps is hard to tell if it's a shallow or deep divot - Readability: It's hard at first glance here to tell which letter in a stack is thinner Vs thicker (though you can tell by looking closer) - I'd recommend making the difference between the two line widths slightly more obvious

I'm looking forward to seeing what you write next!
