I just downloaded (and prompty ended up buying) N+ on Xbox Live Arcade last night. It’s a little puzzley-platform Flash game from a few years ago that the developer, metanet software, decided to release on XBLA, DS, and PSP.
There’s so much content in this game: 500 single-player levels, a bunch of tutorial stages, a level editor, the ability to download user-generated levels, etc etc.
My Xbox has frozen a couple times playing it, but I think that might be because my machine is hours away from a RROD…
