I wouldn't be surprised if the entirety of the improvement is just from the much faster text. From a very quick comparison of the Youtube encodes (I apologize for the large images):
Published run:
This submission:
About 30 seconds of difference within the first 5 minutes of both runs. This run also loses about 4 seconds in that timespan due to fighting two Red Slimes in one battle, where the published run only fights one, so the text difference could be as much as 35 seconds up to this very early point.
This is gonna be rough for whoever decides to judge this... I wish them the best.
To help alleviate that a bit, I'll try to find a day where I can go through both runs and see just how much time is saved/lost in areas that aren't text/version differences. I'll just leave this here for my own future reference:
