Hell yeah, what a cool hack. I think you did really well with the constraints that a single page put on the Fall of Magic system, and the parts you left behind were really smart ones.
Favourite details: There's some fantastic worldbuilding going on in the character creation and locations. I love the leading prompts and the glitzy, grungy, cyberpunky roles. I also love how the Chosen provides a focal point that really concentrates player energies in the one page format, maybe even in a more tangible way than The Magus did.
Maybe next time: The vaporwave cityscape looks gorgeous on the cover, but it's a little busy on the play sheet -- I can read everything, but it's harder on the eyes than I want it to be for such dense text.
But yeah, the writing is great and you should be proud of this piece.
