The biggest reason I've never done it, is because I would want to flesh it out as much as possible. Put a lot of work into it.I can understand that
Ignoring that though, I decided to make a little writing system today. I'm basing it off Japanese's syllabaries. Still working on it.So what makes it different to japanese? Are the horizontal and vertical components unique?
Words will be similar to Japanese, structure wise.
There are a few horizontal components that represent vowels and a bunch of more vertical components for consonants.
What's your goal?
