The game is released.  Still working on marketing material, platforms, and natural languages.  This will probably be an ongoing process.

Keep in mind that a purchase of a full licences for $4.99 USD is good for a single instance on any platform, and with any updates.

So for instance, you purchase a license, and register it to a game downloaded for Windows PC.  Later there is an updated version.  You can simply download and install the latest version, without a hitch.

Or lets say, you want to try the phone version.  Simply install it on the phone, and use your license for that one.  However, that will invalidate the PC version.  Going back to the PC.  Using the license to validate the PC version will invalidate the Phone version.  So one license per game instance basically.
