N

In N, the player controls a ninja who navigates tile-based levels while simultaneously avoiding hazards, collecting gold, and eventually opening an exit door which completes the level. Gameplay involves four keys—a move-left key (default: left arrow), a move-right key (default: right arrow), jumping (default: shift key, though z key is a common alternative), and suicide (default: k key). Combinations of moving and jumping on various types of terrain allow the ninja to perform a variety of movements, such as jumping from wall to wall, climbing up vertical inclines, and sliding down steep surfaces.

Version 1.4 of N contains 100 episodes (numbered 00 to 99), while version 2.0 contains 120 episodes (due to two bonus columns being unlockable after the completion of the main game episodes). Each episode in all iterations of the game features five levels (numbered 0 to 4). N also supports user-made levels. This is done through a built-in level editor called NEd, or the "N Editor". Levels can be added into a game by modifying a text file accompanying the game that contains user level data.
