I'd be down to help write dialogue if you ever do decide to do this. Take a line and tweak it, add or subtract stuff. Of course, you may not want anyone else touching your project, which is 100% understandable and valid.
That might be a good idea; in the demo video it was hard for me to see where the lines were, and an outline could help with that. Maybe make it a little thicker than the current lines if you do?
You could try contacting Brandon on Reddit, see what he thinks.
This project looks really cool, I'll definitely be following it and spreading the word!
