The game doesn't save anything, so it shouldn't be possible for you to get locked out like that. How does this issue present itself? Does it always say the "Echo is infintely secure" message? I'm not entierly sure what you mean since echo locks don't lock you out after a set number of attempts.

No, it was something we did consider but didn't really have the time. Our thinking was that people wouldn't play it for very long since it was a game jam, so we decided to put more effort into polish and other features. If there's enough demand I suppose I could add a save feature in an update.
