In Spider-Man we can control other characters besides its protagonist -with a superhero costume or not- Mary Jane, for example, stars in some sections with stealth and some puzzles that have surprised certain players who are more interested in the action part.
Creative director Bryan Intihar has explained the decision to make this character playable.
Intihar tells Kinda Funny Games that they did not want to make MJ a "damsel in distress" as in past versions of games or movies: "It was really important for us to make MJ contribute to the story." In this way the player could see other aspects of the argument without having to show only cinematics.
Sections were also chosen with stealth to give rhythm to the game: "If we play constantly like Spider-Man, it's a lot of intensity, and it can be exhausting, we think a change of pace would be good".
In addition, Insomniac thought it would be interesting to play as a character without powers in a world full of superheroes and villains.
