Trying to figure out how to test Steam Cloud. I found the following in the documentation:

If you are adding Steam Auto-Cloud to a game which has already been released and you have enabled developer-only mode during the Initial Setup then you must complete some additional steps to test the functionality.

1. Sign in to Steam with an account that owns the app that you are testing.
2. Open the Steam Console by navigating to steam://open/console in your browser.
3. Enter testappcloudpaths <AppId> into the console with the given App ID that you are testing. Ex: testappcloudpaths 480
4. Enter set_spew_level 4 4 into the console.
5. Launch your app from Steam.

I already have developer-only mode disabled, so all I need to do to verify that the auto cloud saves are working, aside from testing, is to run set_spew_level 4 4. This lets me see a log that looks something like this, when the game closes:

Looks like it’s working!
