Interesting take on the theme. I found myself replaying a few times to see more of the NPCs' dialogue. Though, I did notice some of the NPCs said variations of the same thing. For example, one would say "Looks like I'm lost" and another would say "I'm lost." There were also plenty of variations of "This looks like a good place to X" and "Can't wait for the universe to end" type of dialogue, which made a lot of the characters feel too similar to one another.
With that said, the idea of talking to different people and hearing their thoughts knowing the world is about to end is an interesting concept. Add more variety in characters and dialogue and this would be even better. Nice job!
