Here everything is all right, except:
1 - Shadows need to be calculated.
2 - It is recommended that you leave darkened areas at the map edges, like most maps have, because if the playable area is all the way to the ending edges of the map, the map ends in an abyss of blackness, and you can see that abyss in-game and go with units to it.
3 - The map cannot be saved in the normal World Editor, it shows some errors in the spell triggers.
