Can you still work on a project even if you already posted it? I want to make it into episodes. Also how you can make the player able to have a save file so they won't be lost? Thanks!

Hello.

Can you still work on a project even if you already posted it?

Yes. Did you create the game online or in the desktop version.

Also how you can make the player able to have a save file so they won't be lost?

Squiffy games automatically save to your browser's localStorage. So, as long as you always use the same browser on the same machine, without clearing the browser's data, your game will pick up where you left off. (If there's a way to save externally, I don't believe it is built in. You would probably need your own server set up to pull it off, but that's just a theory.)
