I am waiting for steam to review the game, and once it does, it will be available!
Here's the official Ragna Maya twitter account! I didn't do any marketing prior to the game's release on the steam store, so I would be really grateful if you'd follow me on twitter or post or tweet about Ragna Maya!

As of the moment, this is the only entry in the Ragna Maya Saga, but, this WON'T always be the only entry in the Ragna Maya Saga. This, I gurantee you.
