This update introduces a new system for NPCs to be able to speak on their own without forcing the player into a dialog. There is an event-driven chatter system where NPCs can react dynamically to things that happen to them or near them. They can also let the player know when they have quests for them by hollering. NPCs such as Ingot can also gesture with their hands while speaking.

This chatter system will be very useful for fleshing out the story and adding new NPCs. Since the chatter is non-intrusive, I can add as many lines as I want without it getting annoying (hopefully). I believe it makes the world feel much more alive!

There are also some improvements to monster AI-- they now know the slope of the terrain they stand on and their own momentum, which both factor into their wandering behavior.

In addition, I've added a faint global reflection probe back to the game and adjusted the lighting all over the world (again lol).

Changelog below. Have a wonderful New Year!
