From a developer's standpoint, the Metroidvania genre provides benefits to the developer. The genre encourages tight connection between level design and game story, and can give developers opportunities to create an immersive world for the player.[1] Level design of such games can also be challenging as to make sure the challenge to the players of the game is fair and enjoyable, and achieving this goal can be seen as a sign of a success for a developer.[1] Thomas Mahler of Moon Studios, who developed Ori and the Blind Forest, said that was important to design a cohesive world with memorable settings for a Metroidvania, since "players remembering the levels is part of the core design".[10]
