What is Sellsword: Dungeon

Spellsword: Dungeon  (GDD) is a planned succesor to the prototype Spellsword. 

It expands upon the core mechanic of melee combat by implementing into a roguelike game with magical spells and many different enemies to kill, and bosses to challenge you, all whilst unlocking upgrades that empower you.

You play as a mage trying to overthrow a sorcerer king in his castle. after fighting your way through multiple stages you face the final boss, the aforementioned King. The first time you face him, he has a simpler moveset, but once you depose him and take his place, the next incarnation you play as has to fight your former incarnation, with all the spells and magic you had before.
