looks amazing!!! just one little gripe .. think you could smooth out some of the roof borders? i.e.
Unfortunatly, those are quite hard to smooth out
Since they are seperated from the wall sprites they have no pixels to AA with, and if I make them smooth with the framework walls they won't look good on other types of walls.
I'll try to come up with a sulotion for this but I can't promise that it'll work.
