N+, like its free to play flash predecessor N, is a simple but elegant platformer. The purpose of the game is to get to the exit while collecting as much gold in the room as you like. Obstacles include mines, laser turrets, and heat seeking missiles which make escape more complicated. The ninja is a good abstract avatar that anyone can project on to, and all of your abilities will be familiar to anyone who has played a 2-D platformer. What’s impressive about the game is how much playtime it extracts, given that it is a game in which all you can really do is jump. It instead relies on only a handful of obstacles and shifting goals to make a game that you always want to play just one more time. For the purposes of this post, I played N+ on the DS, which unfortunately means I’m just discussing the levels included with the game in single player mode. They took the servers down a while back for DS owners.
The game is fast paced and you can easily die a dozen times per level. Difficulty is a uniquely layered system because the game challenges you in three ways. The first is the challenge that evry player must complete: get to the exit. The second is for OCD players who want to collect every gold piece on the level. The third is the clock, which keeps tabs on how quickly you can beat the level and will kill you if it runs out. Off the top of my head, I’d say the first 30 levels (there are 156 by my count) were easy in terms of completing all three goals. The next 30 made collecting all of the gold pieces a bit trickier. After 30 or so levels like that, getting to the exit is tougher. The final levels eventually introduce the clock itself as a barrier. These are levels in which you are hauling ass just to open a gate and get out. After extended play, you can usually spot which of the three challenges that a level is focusing on trying to engage you with. For example, maybe the exit will only require a little careful footwork and hiding behind cover, but the gold is right next to the laser turrets. Or the gold is generally all along your path to the exit, but there are dozens of robots blocking the exit. Or you just have one minute to win. The more challenging levels can take a lot of practice to beat because often you have to figure out the precise sequence of jumps and wall slides needed to win. It’s not unheard of to practice the tougher levels for an hour or two individually before beating them.
