I would recomend changing the skybox to an actual sky and mark sliding doors and the arcade game on the map. I also recommend using the Wave Function Collapse. Itch user marian42 made a city generator using Wave Fuction Collapse which you can use.

An amusing creation! A few things:
1) It's hard to navigate escalators.
2) It seems often escalators go to single rooms.
Thanks for playing and for your generous feedback! Yeah, the escalators are scaled a bit small. Not sure why they may lead to single rooms more often. I'll scope out the room connector types and see about adjusting the ratios for a future release.
