The charm of this supplement definitely lives in the writing and presumably hand drawn art. For game design and content that aligns with more cyberpunk (and likely more Prospero's Dream for lovers of APoF) this is likely to be a welcome addition as I could see myself using this almost as almost diegetic. I think I might even consider a full edit to make it player facing to be a possible way to take a final version. One of many!
That aside the layout and presentation of the art and information leaves something to be desired and rather than feeling deliberate I feel these aspects would be best served by some polishing.
As it happens in regard to the theme of the jam I can find no relevance to "Ancient Myth" after reading things over a few times. This definitely does not diminish the project in and of itself but insofar as it is a participant of Triptech3 it's a noteworthy issue.
Well done overall with the concept!
