Finally done placing the details in the city, as well as properly setting them up for destruction, etc. – so here's a quick video, to show how things are coming together!
For the large "HOTEL" and "CAFÉ" signs I have put in some extra effort, to make sure they fall apart in a satisfying way when destroyed:

I want to get started on a few trees; it's going to be very trial-and-error because I haven't created any vegetation for the game yet, but I hope it'll go well!
There's a few more details I'd still like to add, too, but I'll have to see how things work out—next month I really should get back to more urgent tasks...
