Simple Face HUD

- Simple Face HUD
  Made by: Sixth

A simple script to show the face of the party leader on the map scene.
Check out the setting area if you want, but other than that, it's pretty much
a plug-and-play script.

Put this script between Materials and Main.

Terms of use:
 * Free to use for whatever purposes you want.
 * Credit me (Sixth) in your game, pretty please! :P
 * Posting modified versions of this script is allowed as long as you notice me
   about it with a link to it!
