See I never let the back button remain because idk how Twine would react to a player clicking back a bunch and then trying to save 😅 and with the way it tracka history I don't know that I could reliably shut off saving just by checking to see if you got to the ending. I get what you mean tho: hopefully the build a save is an okay compromise !!
And, obligatory (both for you and anyone reading this 😂) updates are still in motion !! I don't think I'll need to change much at all for the last chapter but rewrites for the one before that have been way more complex than I anticipated !! But hopefully when the new version drops its just as good 🥰
