As stated in the game's official app store description, Blue Ninja is intended to be a parody of superheroes and "the best of ninja trained spider games". Based on the initial teaser trailer (when it was known as "Superhero Game 2021") featuring a different red and black design from the final game, using music from the film "Spider-Man 3", and the game description's numerous references to "spider heroes", it's very obvious that this game is meant to specifically be a parody of the Marvel Comics character Spider-Man. The visual similarities to Spider-Man in Blue Ninja's early design were most likely changed for the final game to avoid copyright disputes.
