This is weird behavior because we have tested the game carefully on the web (2 browsers, Chrome and Edge), Windows exe and Android devices (a real physical Samsung and LDPlayer emulator), and the game automatically saves without any problem. Sorry for the inconvenience, we tested the game again while writing this and it still works, like many other renpy games, we hope that your devices don’t have some automations that auto-remove renpy’s saves.
Oh I try test again my game that in secure folder in Samsung S25 Plus.
First entering the game: I play(have score) then quit the game
Second entering the game: just like First entering the game(No score) I play again to have score then quit the game.
third entering the game: Have choice to replay or skip the scene and now have score from second run.
I try again by delete and reinstall the game it occurs just as mentioned above.
In my window 11 I didn't repeat the same steps as on the S25 Plus. But i think it occurs as i test on my S25 Plus because I remember that I have score from first play and lost on second play then today Entering the game again for the third time I have the save from second play on third play.
