Step 15: The Final Countdown
It's a good idea to upload a replay demonstrating successful completion, in case people complain that it can't be done.
You'll need to start by creating an account in N -- click "Configure" at the main menu, choose a username and password, and click 'create new user'. You can then use the same username/password to log in at NUMA and activate your account. Once that's done, you're ready to upload levels.
Here's the level that was used in this tutorial:

Once you get used to Ned's eccentricities, making a good N level can take as little as 5 minutes. You get to know by sight what will work and what won't, which moves the ninja can pull off and which are impossible, which layouts to avoid and which make a good base.
We wish you success and happy happy N levels!
