Feel free to address me informally if you don't mind. I played as the Dwarves (my favorite faction). Portals appeared (3 of them), and there was one exit (where the demons came from).
By the way, just a suggestion: it would be more convenient to archive the maps as a single file rather than in a folder. (When unzipping, a folder appears in the "maps" directory, but to run the map, you need the map file itself).
I'm very grateful for the creation of maps for Heroes 5, because Heroes 6 disappointed me.)))
