Then you can update the game directly without downloading the new version?
Sorry if my question sounds silly, but as I said I can not see that menu, and I want to update the game without losing my game.
I use a windows 10, by the way.
Regards!
PD: As for the possibility of adding text, maybe someone from the community would be able to help with that part? I am a programmer myself, but I use php, so I don't know python or renpy at all.

The only way to update is to download the new update each time one comes out.
