Hey there! I think you did a really good job at making a clean-looking, working game without any major bugs (at least for me), so that alone is great. Also, having a working simulation of an economy with corresponding gameplay is not an easy feat, so big props for that!
Now the part I think you could improve the most is displaying the information. Managing an entire economy requires a good overview of all available information and it's not that it's not in the game, but most of it is hidden in menus and submenus. This makes it hard to keep track of what's going on and if you even have to change anything. Some UI elements over the buildings/cars would have been awesome to see what's going on with the people and the jobs. But that's just wishful thinking!
Last but not least, I might be playing wrong but the economy might be too stable. As far as I can tell, none of my workers have quit yet and I didn't really do much for it.
But nevertheless, great job at making an awesome game in such a short amount of time! :)
