Is it possible to make the updater within the game itself? for some reason thats what i was expecting was the updater baked into the game
Since its a renpy game all the executable does is call various renpy labels and functions. If it was a compiled game made in something like unity or unreal, then it could be baked into the application itself. The only way that might be possible is if the updater was an exe that could then itself act as a renpy game, but I'm not sure that is possible.
