This Game starts to get fun when you figure out how to play. For me, i took a couple of hours alongside some online research to figure out how to play.
The tough part in the begginning was figuring out how to connect roads, tram lines, trolley wires. However, turns out it was quite simple. Just click on the trolley line that is already built, & then click on the road ahead that you want to continue building the line.
I also had a tough time passing the first Campaign as they wanted 15% coverage, and even with my extensive coverage, i still was around 50% of that 15%. After many hours, I figured that building lines should be 2-Way(I built 1-way), which means that the line must go back and forth to the same stop area(just like a regular public transport train).
This game's tutorial could be improved too. I know that the developers are currently unlikely to change it right now, but the tutorial is very 'Wordy', which to many new players may not seem interesting. It lacks ineractivivity as well.
Other than these cons, this game still proves to be worthy city builder game.
