This is a really great idea! As the author says, it's a system of rules that sits perfectly halfway between a board game and a role-playing game, managing to take the best of both worlds. I also really liked the two "versions" of the game, the collection version and the survival version.
In just a few pages, there's a solid system of ideas that works well. I was really impressed.
Ran this on stream a while back for the Trans Empowerment Project's Quest Collective, and it is by far one of the best experiences I've had in TTRPGs!
