I have the word "official" in quotation marks, so you know this is super-legitimate.
Anyway, Shift 2 has a neat level creator function. You should be able to tell from the topic title what this thread is about.
No uncompletable levels or joke levels, please. (Unless they're done in really clever ways)
The codes for levels can be very long, and if I'm not mistaken the NGBBS will automatically put spaces in the string of characters to prevent it from messing up the page. So, when you're copy+pasting these into the game, remove all of the spaces.
To start us off, here's a level I made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
