A single-player, 2D action game set atop a sacrificial pillar in the sky, where you fight to be the last survivor. You parry attacks and collect health, shields, and power from fallen enemies to strengthen your character. Quest mode spans 120 levels with 12 bosses, alongside an Endless survival mode and Trials challenges where earning stars unlocks further trials.
