Enemies would enter from the right and your city gate was on the left, I remember them coming from a tunnel and crossing a bridge.

There were fixed spots where you could build (and upgrade?) buildings, some to increase resource generation.

There was a flame turret you could build, but only on one side of the bridge. There were likely also turrets sitting on the gate.

You could spawn and send out units, they were blue. You could also "buy" elite squads of units with exp you got from killing enemies, they were purple.

Aesthetic looked dark/scifi, not too cartoonish
