Question: When I download the newest update, is it okay for me to delete the folders on my computer containing the previous updates? Or would that result in progress being lost?
1. Saves are kept separately from game as far as renpy is concerned.
2. Using saves from old versions in renpy games is not advised. Skipping through everything you've seen on a fresh save is the best way to avoid bugs and errors.
Oh. When I play the new updates, I just make pick up from a save file I made at the end of the previous update and continue where I left off. I haven’t encountered any bugs or errors, but maybe that’s just dumb luck
