Recommend playing this one full screen, played embedded you can't make out the arrows which threw me off.
I enjoyed my time here! If I was to take the concept and run with it, I would borrow a page from Mini Metro: instead of having the city pre-built, have the city grid expand over time so that the user can figure out the mechanics without being overwhelmed.
I didn't feel the theme 'out of control' on this one, but fortunately that's not a rating criteria :)
