+      Big Macrochip HQ (skyscraper) is seen in the distance, player has to get
+      to its entrance.
+  7.  Inside skyscraper, 1st floor.
+  8.  Inside skyscraper, higher floor.
+  9.
+  10. Final boss level: on top of the skyscraper, player climbs up in a spiral
+      towards the roof. There is a boss (or two) on the top with a few smaller
+      ones, the exit is blocked by a lot of trapped warriors which the player
+      has to slowly kill, which means he has to first get rid of the other

+- boss level: skyscraper top, player goes upwards in a spiral along the OUTSIDE

 - two levels could partially overlap, e.g. level one, a city, could overlap
   with a later city level, the player could recognize he's e.g. on the other
   side of a channel or a wall that he was before
