Your map is not working. When you enter the editor and place any object on the map, the map becomes unplayable. If you add another hero to Gotay, Gotay's death doesn't mean the end of the map. That's what I meant. And there's a Dungeon on the map, which means the victory conditions are set incorrectly. When you try to write a script for Gotay, the map breaks after saving. So, keep practicing, keep learning, maybe you'll get the hang of it.

For starters, write the map name in English in the file name. Here's a little tip.

No. Even renaming the map doesn't allow you to work with it in the editor. When checking the map, about fifty errors pop up; check the source files.

If you play it as is, the hero Gotay is too weak, and the Walkthrough of the map becomes a pain. I've lost three times this morning. So, I just wanted to slightly increase Gotay's army. But no. Well, maybe it will work better for someone else.
