Odallus: The Dark Call is a 2015 action-adventure platform game in the vein of Castlevania III: Dracula's Curse, developed by Brazilian indie studio Joymasher.
At the castle's throne room, their leader reveals himself to be Haggis' son, somehow aged to adulthood and claiming to have lived a thousand years.
He offers to share the power of the Odallus with his father and rule jointly as the new gods of the world, but Haggis refuses and slays his son.
After the credits, Haggis awakens in a strange land, where an ominous glowing eye forms in the clouds, and a voice encourages him to craft a new world from the darkness inside of him.
With the game having several role-playing elements, Haggis can upgrade his equipment and abilities by finding items hidden throughout the various levels.
[9] Destructoid gave the game 9/10, saying, "Odallus: The Dark Call is a worthy addition to any metroidvania fan's library and is worth the asking price.".
