Hey! Guess what! I DID make a game like this again haha. I have released the spiritual successor to this game, Conversations, and it's now called CANNIBAL COURT (https://loomnorth.itch.io/cannibal-court). This version has 3 characters that you're trying to learn about/befriend/manipulate, and you're trying to play them off of each other (each NPC actually responds to what other NPCs say).
Anyways, since you enjoyed the world and mechanics of Conversations with Cannibals, I hope you enjoy CANNIBAL COURT too! Let me know what you think!
