Added sound effects to the intro, put the "Intro.ogg" file in the BGM folder. If you havent changed anything within the script, you can just replace it with the new one. If you modified something in the script, just add pbBGMPlay("Intro") right next to the line "def main" and you're good to go.
the Sync of the battle sequence may not 100% perfect, but that's due to the own script's speed, so there's not much i can do about it.
Bug (?): The intro sounds will continue to loop in the load screen when you open the game from DEBUG mode.
It stops when you load or start the save and this doesn't happens when you open the game from the .exe, so i don't think it's really an issue worth fixing.
