Introduction

As a game developer on itch.io, ensuring that your players' save slots remain independent is crucial for a seamless gaming experience. However, you may have encountered situations where games share save slots, even if they were created by different developers. In this article, we will explore the reasons behind this issue and provide you with practical solutions to keep your games' save slots independent on itch.io.

Understanding Save Slot Sharing

When playing itch.io games on Firefox, you may have noticed that some games share save slots. This can be frustrating, especially if you're playing multiple games that require separate save slots. Save slot sharing occurs when two or more games use the same storage mechanism, such as the browser's local storage or a third-party library, to store game data.

Why do games share save slots?

There are several reasons why games may share save slots:

Lack of awareness: Game developers may not be aware of the potential for save slot sharing or may not take steps to prevent it.
Shared libraries: Games may use shared libraries or frameworks that store game data in a way that allows multiple games to access the same data.
Browser limitations: The browser's local storage or other storage mechanisms may not provide adequate isolation between games, leading to save slot sharing.

How to Keep Your Games' Save Slots Independent

To keep your games' save slots independent on itch.io, follow these best practices:

1. Use a Custom Storage Mechanism

Instead of relying on the browser's local storage or shared libraries, consider using a custom storage mechanism specifically designed for your game. This can be a simple JSON file or a more complex database solution.

Benefits of custom storage:

Improved isolation: Custom storage mechanisms provide better isolation between games, reducing the risk of save slot sharing.
Flexibility: Custom storage allows you to design a storage solution that meets the specific needs of your game.

2. Use a Third-Party Library with Save Slot Isolation

Some third-party libraries, such as the IndexedDB library, provide built-in support for save slot isolation. These libraries can help you store game data in a way that prevents save slot sharing.

Benefits of third-party libraries:

Convenience: Third-party libraries can simplify the process of storing game data and provide features like save slot isolation.
Community support: Third-party libraries often have active communities and documentation, making it easier to troubleshoot issues.

3. Use a Game-Specific Storage Folder

Instead of storing game data in the browser's local storage or a shared library, consider using a game-specific storage folder. This can be a folder on the user's file system or a cloud-based storage solution.

Benefits of game-specific storage:

Improved isolation: Game-specific storage folders provide better isolation between games, reducing the risk of save slot sharing.
Flexibility: Game-specific storage allows you to design a storage solution that meets the specific needs of your game.

Conclusion

Keeping your games' save slots independent on itch.io requires awareness of the potential for save slot sharing and a willingness to implement best practices. By using a custom storage mechanism, a third-party library with save slot isolation, or a game-specific storage folder, you can ensure that your players' save slots remain independent and provide a seamless gaming experience.

Additional Tips

Test your game: Test your game thoroughly to ensure that save slots are not being shared with other games.
Communicate with players: Communicate with your players about the importance of save slot independence and provide guidance on how to prevent save slot sharing.
Stay up-to-date with browser changes: Stay up-to-date with changes to the browser's storage mechanisms and adjust your game's storage solution accordingly.
