The little horn things are for plosives, the little stroke to the right at the top is for fricatives, to the left is for nasals, and the little loop thing at the top's for approximants. The hollow circle represents voicing. loop thing on the tail is bilabials, tail loop that crosses over to the right some more is labiodentals, crossed tail is for dentals, but I only made the unvoied dental fricative with it, and represented it with Q. The curved tail to the right is for alveolars, to the right is postalveolars or palatals, and the hooked tail is velars. /r/ is written as a sort of diacritic that's put under the vowels it comes after. The y key works as a skeleton vowel when an r follows a consonant, or as a schwa. I also decided to write /h/ as a velar approximant, and /l/ as an alveolar approximant. You're also meant to capitalize each word in the font, so the connecter line doesn't poke out.
