Previously, the level you were building in the Level Editor would be wiped clean every time I released an update. This is due to the way Unity WebGL games store data in the browser and the way sites like Itch.io hash their file names.

My solution was to implement a custom storage system based on browser Local Storage. It's not perfect as your level will be wiped if you clear out your browser storage, but it should serve as a more reliable way of storing your level long-term. That said, I still recommend you periodically export your level code to a text file.

Cloud save is on my roadmap!
