The game is a 2D fantasy single-player action RPG in which the player takes control of an undead king. The player must fight their way through five enemy-filled areas and defeat the final boss to win. To progress from one room to the next, the player must eliminate all enemies in the current room. By defeating enemies, the player collects souls.
These souls can be used to cast powerful magic spells, which is important since different enemies have different weaknesses. Knights are more vulnerable to magic attacks but take reduced damage from melee attacks. On the other hand, the mage and the king are immune to magic damage and are instead more vulnerable to melee attacks. To overcome all enemies, the player can ask an NPC for help to make reaching the final boss easier.
