Saving polytoria games

How do I ssave polytoria games, I clicked files and saved to files, I opened back up and nothing. how do I save polytoria games?

you can only open backups from the creator
just click file -> open
also dont trust autosave and use ctrl + s to manually save from time to time

polytoria autosave saved my game from being lost to time wdym don’t trust it

autosave only works while you're building, but almost never while scripting
that's why you shouldn't rely on it too much
