This script is very much a Phonological Cypher, being an easily written, phonetically constructed alphabet like others in that series. Some letters resemble slightly those of Burmese and/or Thai; not such a bad thing.
The consonants have clues to the manner of articulation in their shapes, and appear to come in sets. In particular, a dip in their top or base indicates devoicing, a vertical stroke at the left/front indicates a fricative, and an above-and-front stroke indicates /-r/ or retroflex behaviour. The chart here has rows in order of region – labial, dental, palatal, velar-glottal.
Vowels shapes attach to the curved back of their consonants, here shown with /n/. There is an extra dip in those with lip-rounding. Most diphthongs have their own distinct shape, but the three on the last row (and some other possibilities) are composites. The /a/ can represent schwa, especially in broadening diphthongs. Long vowels, if required, can have an acute accent above (as in Old English).
There are some consonants which, when connected to vowels, show they have strokes strategic to that purpose:
There are four levels/types of pause, representing comma, period, exclamation and question-marker.
This is a transcription of the first line of Shakespeare’s sonnet 18, for comparison with versions of SIGIL etc.
Shall I compare thee to a summer’s day?
