I was wondering if anyone had had any experience with this library.
Nope, I think it's a new project. Very confusing for me though because my project is also called OneJS (onejs.com), which is very different and provides Javascript support for Unity.
Oh wow! I saw your project while looking for this project. It's unfortunate that this project has such a similar name to yours. It's still pretty early; maybe they'd be open to rebranding. Best of luck!
