I'm working on a new cutscene and I found out the system that shows NPC sprites while in dialogue (One of the first scripts I wrote) was incredibly bad. So I rewriten it from scratch. Now it is about 40 lines instead of 500. NPCs can now talk between each other plus adding new NPC sprites doesn't require any new code. And as a bonus, it doesn't require me to go through any text.
I will try and go through previous cutscenes and make them take advantage of this system.
