I had a whole project related to NPC dialog generated with AI before the jam. I was thinking of using that, but eventually realized it didn't really fit the play style so I kinda abandoned that idea.
But now, I'm reaching the end of the jam and have a bit of time left, so I might take on the challenge after all!
The idea is simple. Just inform OpenAi about what's happening, and let it generate a piece of dialog. I think this could lead to fun interactions
