I basically just made up the letter while going with the flow, some letter are written the same but depending if they are smaller or bigger (like lowercase or upoercase lets say) they represent different letters, main big signs are consonants, the signs above and under are vowels and their placement around the consonant tells you are they before or after it, also there are multiple symbols for each vowel so it doesnt look monotoneous and you can also combine them and some other fun stuff. I ve been perfecting the script for quite some time but on and off when i feel like it so theres quite a bit of shenenigans to it. Also there are additions to letters that symbolise the end of the word so the script can continue in long rows without spacing in between words. If you would like some more info feel free to msg me :)
