Kien

An action platformer with RPG elements, developed by AgeOfGames (formerly PMStudios) in the early 2000s and left unreleased until 2024. Two young apprentices must fight the evil corrupting the planet of Malkut and uncover the secret of Kien across 23 demanding levels, in a non-linear structure that lets players choose their route. Its lead designer describes it as a very challenging, almost pre-souls-like game with intense fights.
