Just curious, has anyone tried mapping with Old School Modern, Time Fantasy and Crazy Leen's tiles together? Do they work? I got both OSM packs from bundles and for the first time I'm actually considering games in this style.
I just successfully tested changing music by region, and changing it between continents on the world map after getting on/off the airship. I had to override the default audio transitions with eventing to make it change smoothly but it worked.
