Dammerlicht is a game based around the many worlds theory, where the actions of the player create alternate universes and allow you to experience each potential path the game world could take.
You could join the king, unlocking a level which is the universe where our hero joins the king. Then you could attempt this level again but instead kill the king, unlocking a new level which is a completely different universe than the previous one since in this universe, the king is dead.
Not every single action in the game has a different outcome, but the player has the option to attempt to unlock every possible outcome of this world. Each path will be different and in each one of those, the player will experience different things: pure combat, love story, research, treason, or even all at once!
