For all of you who don't know, N+ is an old school like game that is based off of the popular flash game, "the N game". The game is easy to learn, but insanely hard to master(I once died 1000 times in a level),and the user made levels are somewhat hard (my dark maze level is particulary evil) There are 3 versions, the Xbox live arcade version, nintendo ds, and the Sony psp (I own this version)
