Again, thank you for playing! I'll check the big mountain map, maybe I didn't notice some passability issues! >_<
As for the last scene (SPOILER)...
The dialogue isn't that important. The cutscene needs to show, after lot of years, that the world situation is better (there're now trees, flowers, river, ecc... ) thanks to the actions of people, so nothing is lost. Only time can heal. ☺️
