## What's New

Players can now **walk up to NPCs and talk to them**! 

### The Flow
1. Player walks near an NPC
2. Blue prompt appears: "Press E to talk to [Name]"
3. Player presses E
4. Person-chat minigame starts
5. Conversation happens
6. Minigame closes, player resumes

## Implementation Summary
