There are a lot of really neat and evocative ideas in here with separating the players into an Agent and a bunch of Sidekicks - I can see a lot of fun emerging organically just by players leaning into their identities.
The box-/node-maps for the encounter locations are innovative, but I think this is where the constraints of sticking with a zine format come through - for example, having all the information on p.5-8 all on one spread would make running that encounter very very smooth.
Overall though, this is a really strong FIST op and a fun twist on the format.
One thing though, in the downloads, there's no pdf of the whole thing - just the handouts. The whole thing is there, but as an .afpub file, and while I have Affinity so I can open it, a bunch of formatting and fonts were broken since I don't have those resources on my machine.
