Some things about N can vary by opinion. For example, some consider it to be Grade A [[PlatformHell Platform Hell]] while others consider it to be a relaxing, easy game.
----
* BreatherLevel: The first episode of a column tends to consist of these. Especially compared to the [[ThatOneLevel last episode of a column]].
* DifficultySpike: Despite Metanet's claims of them throughoutly balancing the levels in all the episodes and grids, this happens several times in ''N++''. In particular, the final levels of episodes C-14 and C-18, Polyrhytmic Pit and Earthdate 2264 respectively, are generally considered to be... oddly misplaced in the grid, as dodging a bunch of micro drones in a really tight corridor is actually harder than it sounds. C-14 forces you to do that for 30 seconds straight, without dying. And it's a requirement to just beat the level, gold collection notwithstanding!
%% ZCE* GoodBadBugs: Oh so many. Oh so very many. To the point where people try to create levels revolving around them.%%
* ThatOneLevel: Mostly depends on the player, but it is flat out guaranteed that there will be at least two per column.
** 88-4 and 96-4 of the original still haunt some tropers in their sleep.
*** For 2.0, 99-4 and [[spoiler:a9-4]] are also nightmarishly difficult.
** Naturally, having over ''2 thousand levels total'', N++ has a lot of examples of this:
*** The infamous "Go Fish", a random mess of toggle mines and gold strewn about an open area. While easy to beat, getting all the gold is something else entirely.
*** Appropriately titled "The Legend of the Gold on That One Level" is one of the early examples. All the gold is tucked away in single area in the bottom left of the level. Merely getting to the gold is an exercise in impeccable timing; you have to pass mines, drone trains and a rocket launcher InASingleBound or two. Then, when you finally get through, you'll find that the gold is ''toggle mined''. Good luck getting out, and then passing those drone trains and rocket launcher ''again''.
*** "[[WordPureeTitle Schnorgled]]". You have to WallJump between mines through a shaft patrolled by drones ''in both directions''. And if that's not bad enough, the exit and the switch unlocking it are on ''opposite ends of the shaft'', making you traverse it ''twice''.
*** Let's just say any final level in the last episode of a column tends to be this.
*** [[spoiler:Secret challenges]] can easily make you despise levels that you've never found frustrating before. The classic example is "Prosumer": a relatively chill level built around a grid of gold, with toggles behind each piece. [[spoiler:Now try collecting all that gold without triggering any of the toggles. It's much harder than it sounds]].
* SugarWiki/VisualEffectsOfAwesome: N++'s print-based, sleek art style is a beauty to behold. Especially with the game's [[http://blog.us.playstation.com/2014/05/14/n-on-ps4-graphics/ custom vector renderer]], which gives an immaculately smooth image equivalent to ''256x MSAA''.
