Please note that in order for the game to be saved, you must use
the save feature in-game (unless of course the game itself
autosaves), then press the save button here (Or autosave must
happen).
These saves are only for in-game save files. If you want to
be able to save at any time, use save states.
Saves and states are saved in your browser's indexedDB and are
automatically readied every time you visit the page. You only
need to use export and import for backups.
