Scirra Arcade Question

Hope this isn't a stupid question, is there a way to upload a game but not publicly so you and other people you allow can test it before you release it publicly?

The Arcade is meant to be a showcase for Scirra primarily, and secondly a showcase for the user. What you suggest would defeat that purpose.

Instead, why not use one of the many free hosting sites such as Dropbox, etc, if you only want to share your creation between certain people.

It was more for testing the high-score part.

Thanks anyway.
