The answer to this is yes and no. The base is the Tome, but it has limitations. On the one hand, it only handles byte values, which is not yet a problem, but narrows down the possibilities. Another limitation is that the editor assigns the same value to each tile, so I cannot manage multiple events for the same tile. The game uses only two layers. The first layer (standard TOME MAP) displays the Tiles. The other (not standard VAL) layer handles figures, walls, animations and basically all other events present in the map.
The twist in useage is that I work with TOME, but I use Turbo Scene for draw tiles, because it's faster, and I use the tome map command to query the value map. So I don't use TOME for what it was designed for... but it serves the purpose.
