N+ creators Raigan Burns and Mare Sheppard in their response blog titled "In Defense of the Apparant Shitstorm" write:
Since the February release of N+ on Xbox Live Arcade, the developers at Metanet have apparently locked themselves away in a secret underground Toronto location, cranking out new levels like true design ninja.
At the 2008 Game Developers Conference in San Francisco, Mare Sheppard (Metanet Software Inc.) and Nick Waanders (Slick Entertainment Inc.) gave a presentation about the development of N+ for Xbox LIVE Arcade. These are the slides used for the presentation.
N+ always intended to let players upload custom levels for anyone to download, but Microsoft nixed the feature at the last second.
PS3Fanboy reports that N+ creators Metanet confirmed a PSN version of N+ (recently released on Xbox 360) is definitely in the works. However, it will not appear on the service any time soon. "Yes, however due to an exclusivity clause in our XBLA contract, it may not be for a while."
