I suggest archiving the files so they're not too many.
I use Ren'Py for my vis novels too so I know.
Here is some code you can use:
init python: # Declare archive files build.archive("scripts", "all") build.archive("images", "all") build.archive("audio", "all") build.archive("others", "all") # Put script files into the scripts archive. build.classify("game/**.rpy", "scripts") build.classify("game/**.rpyc", "scripts") # Put images into the images archive. build.classify("game/**.jpg", "images") build.classify("game/**.png", "images") build.classify("game/**.webp", "images") # Put audio into the audio archive build.classify("game/**.mp3", "audio") build.classify("game/**.ogg", "audio") # Put other files into the others archive build.classify("game/**.ttf", "others") build.classify("game/**.txt", "others")
