Step 13: Saving Your Level
To save your level, hit the "Home" key to get back to Ned's menu, then hit "PgDn" to dump your level data into the upper textbox (labeled 'Level Data'); that's where your level data resides.
You will need to click in the box, then select all and copy the text: click, ctrl-A, ctrl-C.
Paste your text into the userlevels.txt file that accompanied your download of N -- this will allow you to play your level in N. Adding a level to the userlevels.txt file must be done in a particular way, so please read the file to find out how.
You could also paste it into an Excel spreadsheet or plain text file for later revision.
The names of N levels is part of what makes them great. It's an art, really. To title levels, Metanet Software uses a unique blend of pop culture references, favourite quotes, the names of fictional characters and interesting historical figures, ridiculous/funny sayings, alliteration, horrible puns, a dash of sarcasm and, where possible, a reference to the level's theme. There's a list out there somewhere -- read through the names and prepare to laugh until hospitalized.
Here, I've called my level "hurry hurry hurry", which unfortunately isn't particularly funny; however, interesting nonetheless. The level resembles three 'H' shapes, hence the repetition of three words beginning with 'h'. 'Hurry, hurry, hurry' (eg. 'step right up!') is a phrase used by ancient hucksters who were more often than not, con artists. Con artists are cool. The idea of needing to hurry is integral to N, so that fits well. I'd rate that name only a 6/10, but it'll do for now.
When your level has been saved, it's time to try playing it.
