2.1.0

Author: SillyLix
Unity Version: 6000.0.61f1+
Download: itch.io
Change note: Minor update with new features and improvements.
Date Released: 2026.05.05

Added

• Added support for WebGL builds with a new SaveWebGL File I/O handler that uses PlayerPrefs for storage. (I may update this to use IndexedDB in the future, depending on how much time I have)
• WebGL Demo scene.
• added Newtonsoft.Json to be download via Unity UMP if not already present (you can't import lix save system without it so it will ask you if it's okay to download it when you import the package)

Changed

• Change in IFileIO.cs (Interface) bool DeleteFile(GameData data); -> void DeleteFile(GameData data);
• Updated documentation to include WebGL instructions and examples.
• Changed the license for the asset to be the one provided by Unity Asset Store if downloaded by Unity asset store (preparation to release on Unity Asset Store)
