since they are taking inspo from the grid system (and making it seem like peak urban planning), i wish the author had taken inspo from La Plata, Argentina. i think La Plata makes the grid system look aesthetically pleasing and not boring, plus adding diagonals just makes sense. I agree with everyone else about there being a lack of greenery, sewage systems, building variation, and commercial/public buildings.
also, this manga has a great premise, but the plot and characters feel one-dimensional. idk its missing a certain spark that would make it interesting. I see potential ofc but it feels mid.
