When you say "bundle up" all the files contained to put a finished story up on Itch or other places, I assume you mean basically re-zipping all the files in the Folia folder (the Folia.exe file, the finished story.lua file and all the added assets) and offering it for download?
That would mean I'd keep my original Folia zip file from Itch for creating new VNs and such, right?
