Hello again!
It can be a bit ambiguous, but the "Released" status is usually reserved for fully finished and complete projects. If you intend to release the full game (whenever it's complete) on this same page, "In Development" might be a more accurate status to depict that the story you're telling is still being worked on. However, if you intend to upload the finished game on a separate itch page and don't want to mess with this one any further, perhaps just state on the body of this page that this is the finished demo but that the full game is still in development and will be published at a later time. This is just to help minimize confusion.
Thank you for updating the platform tags! Best of luck in your development journey!! ^.^
