itch.io's CDN change may affect your saved progress (if in-browser-only)

https://itch.io/t/3099694/notice-for-html-game-devs-upcoming-change-to-cdn-domain

Games that used save game state within the browser will lose all their save data, as things like localStorage are tied to the domain of the executing JavaScript code – Unfortunately there is no way around this limitation. You will either need to provide a way to export and import save game data in your game, or you will need to integrate with a hosted API that provides save data storage

Just in case you have temporary saves in your browser, be aware that you might lose it soon if not exported to disk as a .save file for later import. However, I’m not sure what will happen once itch.io changes to the new Content Delivery Network. So, just a heads up about potentially losing some saved progress.
