replays are ended with $ renpy.end_replay() and can span multiple labels
you can have multiple end points for a replay as it will stop when every it hits one of them
just be careful that they don't interfere with other replay areas
HTH
Thanks! So they ends with $ renpy.end_replay(), but starts with the simple label name, am I correct?
yes that is correct
also the player has to have played past the label to unlock it in the replay gallery
perfect, thanks
