Gameplay wise, Ori is a so-called Metroidvania. You have to jump and fight your way through a wide world and, step by step, unlock new abilities that lead you into previously blocked areas. The melancholic atmosphere and deeply sad story (in some places) are what makes the game special. Even if the optics don't make you guess it immediately, Ori is not an easy game. Many places will demand you to use all your skills and prove what you are worth.
