Hey, thanks for playing!
To be clear it is just JS app where background is procedurally generated from graph (intersections = nodes and street = edges, plus Kruskal's and Dijkstra's algos are used to set patrols and check passability), it is drawn on PixiJS primitives (boxes, straight lines for streets and some random 'noise' lines to avoid just gray-boxes);
The characters are also generated but using this tool https://github.com/liberatedpixelcup/Universal-LPC-Spritesheet-Character-Generator, so they do look 'synthetic' but as I know their generator is not ai-based (my failure if it is and I did not noticed it) unlike lets say https://pixie.haus/ where they really look as ai generated (and ther are lol);
Sprites and sounds are also just found on free sources
Yes, I can agree it might look like AI because we stuck on limited dark color palitra but unfortunately we did not come up with anything more suitale for night city atmosphere haha
(to be honest we did use ai help in some unobvious ingame math and for graph polishing because auto generation was the totally new experience for us, but I do not thing it would surprise anyone today)
(ps: sorry for such longread)
