This game is rated ESRB: Everyone 10+ for Mild Fantasy Violence, Mild Blood and Mild Language.
N++ is a fast-paced, action-packed platformer set in the distant future. You play as a ninja, darting through obstacles, narrowly evading a slew of inadvertently homicidal enemy robots and collecting gold in a minimalist, sci-fi world. N++ is all about smooth physics, deftly controlling the speed and inertia of the character, and the awesome feeling of fluidly moving through each level.
