From a developer's standpoint, the Metroidvania genre also provides benefits. The genre encourages tight connection between level design and game story, and can give developers opportunities to create an immersive world for the player. 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. Thomas Mahler of Moon Studios, who developed Ori and the Blind Forest, said that it was important to design a cohesive world with memorable settings for a Metroidvania, since "players remembering the levels is part of the core design". Large-scale development in this genre requires one change in the player's abilities to be tested more rigorously throughout all of the levels. Ori and the Will of the Wisps executive producer Daniel Smith said: "I don't think people generally consider how difficult it is to make a Metroidvania game. Everything is so interconnected that if you change one aspect of the game, it's just inevitable that it's going to influence the rest".
