To make it easier for players to save and load their progress, you can create a save menu. Here's an example:

If you want to share "official" saves (e.g., for bug testing) without triggering warnings, you can add specific keys to your game's configuration.

The "Save Token Security" system is a security layer designed to prevent "bad actors" from using malicious save files to run unauthorized code on your computer. Because Ren'Py save files use the Python format—which can technically execute code—Ren'Py now signs save files with a unique "token" specific to your machine.

If you are trying to use a save editor or a save from a different device and the game blocks you, players often resort to a "bypass" by modifying the engine files.
