N is a game based on Ninjas, for no reason you must collect gold, if you don't... you die. Although the game is free it is more fun than some games that I've payed fifty dollars for. The only three things you can do are move left, move right, and jump; but with the games excellent graphics and complex physics system, these three things can be combined any number of ways. To get through each level you have to find the door switch, press it, and unlock any other doors in your way, after that go through the door.
With its 500 levels plus how ever many users created (an option that you can use if you don't want to play the levels made by the developers) and the ability to make your own (press ~ or / at the main menu) this is a truly great game.
So head on over to http://www.thewayoftheninja.org/ to download the game for free. Oh and it takes up almost no memory on your hard drive.
