An interesting idea - the first time I played I spoke to one of the NPCs and they kept chatting and chatting, even after I said "goodbye". Very realistic mimicry of some people! I gave it another go and had some more reasonable conversations. I think the feed could be more focused on the people around me, I got a lot of info about other NPCs talking to each other and "feeling emotional". It was a novel concept though, nice job!
Some technical tips with Itch + Unity WebGL: Add 42 to your Itch.io height to fit in the Unity fullscreen bar, and uncheck Itch's "enable fullscreen button" option. It masks Unity's native one, and doesn't actually affect the playable space.
