I asked because I currently use an excel sheet background, and icons that I had already reworked, but I am a fuckin perfectionnist and find the result to be far less nice than yours.
Now I am trying to vectorize the tiles that were brought by a user here, to come along with the Tilesystem soft, but it is very hard to get nice pics of rooms with minimum detail of the ground, without having dark background that is not very legible. Perhaps should I convert the tiles in black and white before vectorizing...
Anyway your new rules and remix of quests might be nothing but sweet candy to an Evil Master
