hello,

I am developing a game, I didn't finish yet but from time to time I start it up to make some trials.

I tired "save" command to check if it is saving, when I write this command, first I see "game saving", but then "failed to save game" appears. What is the reason of this problem? what did I skip to add?

Are you using the online editor? If so, then you can't save a game while testing it from the editor. But you will be able to once you publish it and run it from the site (you can make it private while working on it, to keep others from seeing it until it's done).

If it's the Windows desktop editor, then more info would be useful, like whether you see the File dialog that allows you to enter a name.

Thank you very much.
