FYI

As most of you probably know, I'm leaving this post for those who don't. In the hidden section, it shows stages besides levels, but there's no stage distinction in the game. You can just consider them as area order. The outer area is 1-1, the residential area is 1-2, and the industrial area is 1-3, and so on. To move to the industrial area, you need $4.8 million at level 75, but until level 80, the maximum asset you can hold is $4.8 million. So, if you want to proceed comfortably, I recommend reaching level 80 and going safely. Your maximum held assets increase every 40 levels, so please keep this in mind.
