I am very sorry to hear that. What browser + version are you using? The game uses the IndexedDB API to store its save games. If you are using Chrome then check your third-party cookie settings. The default settings usually remove all indexed databases whenever the cache of a page is cleared.
i get an error on firefox :
"An error occured running the Unity content on this page. See your browser's JavaScript console for more info. The error was:
SecurityError: The operation is insecure."
