The game is described as a "compact action-RPG" that also appears to have some rogue-lite elements. You'll play as a hero that sets out to defeat the evil Mormo and her army, but all experience/power you gain during the course of that adventure goes into the sword you wield. When you perish, you'll start off as a new hero that picks up the sword and inherits that experience/power. However, the successes and failures of the previous hero impact the world the new hero faces. It's a little reminiscent of Rogue Legacy, but taken to a higher degree.
