Beton City [dream of the past]

BETON CITY. You have woken up in a place you are not familiar with. From the looks of it, these buildings are many years old, and the people have long since left this place. However, you vaguely recall that this was a city.... I guess. Get to "paradise", to the very top of this structure! Black (first) level - the city slums, were abandoned the very first. Blue (second) level - the city's beach, a landmark. People tried to keep it clean and tidy to the last. Yellow (third) level - the industrial zone of the city. White (fourth) level - "paradise", a place for the richest people of the city.
