I can't tell if this is actually a new project or if you forked, extended, and changed the license of an existing MPL 2.0 project. The latter would be a bad thing.
You have a commit titled "Full rewrite!!" but I'm not about to go do a comparison to see how "full" it is. If it is indeed a complete clean reimplementation then I would recommend making it a new project so it doesn't look like you took someone's FOSS code and relicensed it for yourself.
