N is an award-winning 2D action/puzzle platformer reminiscent of lode runner: you're a tiny stick figure running around in a puzzle-y world inhabited by enemies. But in N, there's a twist: the ninja is driven not only by a thirst for gold, but also by a sweet physics simulation.
Expect to encounter death frequintly, animated with bitchin' ragdoll physics.
N includes a built-in level editor, called Ned. You can make your own levels to share with the community or hoard for yourself. Infinite levels, woo!
