I was initially surprised as to why this game exists in the way that it does but after doing a little digging I found out that it takes after a mobile game that the devs previously did and by the dev's own admission, is a little side project to flesh out the back story. In that context, I don't feel like dunking on this game too much but I will briefly mention why I don't think this is worth playing unless you really liked the first game.

Mile 0 lacks substance in terms of story, what backstory explanation it adds is minimal and what new content it adds is forgettable. Primate reason is that the characters fall completely flat, barely straying from how they can be described in a sentence. Admittedly you can influence how the 2 main characters think but it hardly matters given how dull they are. To top it off, it caries over the juveline half assed political theme from Road 96 too.
The environment art might be alright but the character models look janky and oddly oily, to the point where Zoe looks worse here than the original game. On the gameplay side it combines bare bones exploration and subway surfer like minigames which are somewhat reminiscenet to Sayonara Wild Hearts, to its detriment I say cause it's nowhere near as good.
At least the soundtrack is good, they even managed to get a track out of The Midnight, one of my favorite bands!
