1. Access to the dungeons needs to be implemented differently.
2. When the hammer is obtained, the quest should be completed, and a new quest should appear, like "use the hammer."
3. The dragon utopia needs to be fixed.
Overall, the map is very good, and the plot and ending really make you want to know what happens next.

And also... the text should be made more polite; it's a bit too colloquial.

Regarding the mine, I have some suggestions. Create a video cutscene with the appearance of the dwarf hero. The first time, the dialogue is about asking the orcs not to invade their territory, and the orcs don't invade. The second time, after the mountain brother is found, there's another dialogue and video cutscene, and the orc attacks and then ends up in the mine. Also, the discovery of the mountain brother needs to be implemented differently.
