And Donald and Goofy (iirc).In the atmosphere.
There are quite a lot of games like that, just the hero and the mission. Kind of like a Silent Hill setting, without the gore and horror.
The main reason why I love End of the World is that there's no secondary route nor npc interaction, it's just you and the darkness.
Yeah, I'm aware there are many games like that, but again: Where's the fun in that? Nonexistent. Imo anyway. I don't want to play a game where you just gotta run through the world and beat the enemies and nothing else.
