Hey Drifty, I can think of two things straight off the bat when playing this.
In the games main folder, open your package.json and change the size of the window to the same settings as the resolution settings in your plugins. This will stop it from resizing as soon as you open it, which is a glitchy annoying thing.
Next thing; because of the overall length of your dialogues, if you're using Yanfly's message core, auto-wrap your texts. If you need a manual line break in the message, us <br>, and in the message core parameters go to 'Default Width' and change it from 'Graphics.boxWidth' to something like '(Graphics.boxWidth / 3) * 2' which will shorten it instead of a massive message window to something that more compliments the shorter text.
Chances are I'll be finding other things, so i'll keep you posted :)
Still love this game, love watching you originally create it, and watching you update both recorded and live. (You're on too early for me usually to watch you stream it, but occassionally I manage to catch ya).
