I am going to try to add thinwall sprites for all of the wall types. The former thinwall sprites were so large that they completely hid the tile behind them, so I’ve reduced the height of the new ones a little bit. The color scheme of the new walls is inspired by the Sunrise real robot cartoons of the 80s.
There are many improvements that could be made to the map display. As seen in the door tiles above, there’s some mismatch between the walls and the ground tiles underneath them. This could be fixed by giving ground types a border, so the tile next to the door could have carpet on one side and dirt on the other. Borders would also fix the patchwork problem ground tiles currently have. Another big improvement would be to add signs or some other way of telling the purpose of a building just by looking at it. Although some walls are already associated with specific businesses (shop walls, garage walls, hospital walls), this is not applied consistently and doesn’t cover all building types.
