Hey I'm a fan of TT!
But, one thing that I always wanted that exist is the Airport!
Everytime I used two parallels streets and radio tower to make an airport, but I found this forum, so I wanted to share with you my idea. Perfect job dev!
Could you please show the rest of the city? Considering the minimap it looks interesting. Also I want to add that for me it would be better to have underground and trams first, I can wait for the airport longer. And of course more kinds of skyscrapers.
