N+ is an exciting throwback to 2D platforming that improves upon the formula in almost every way. Whether you enjoy your action online or off, you'll get plenty of enjoyment for your money. This is one of the best XBLA titles currently on the market, and is heartily recommended for fans of action games, platformers, and cooperative play.
Great use of physics; solid platforming; abundance of content for single and multiplayer modes; entertaining soundtrack; level editor included.
Can't share user-made levels online; blistering difficulty of some levels will drive you insane and make your hands ache.
