Klei EntertainmentYou never completed: Anything past the middle set of levels. One for the difficulty books, N+ is a charming little platformer with pixel-perfect sections tighter than a hipster's jeans. Taking a very minimalist aesthetic and giving you a character that's just a little black stick man with a bandanna, early levels start off simple enough with you perfecting the floaty physics given to you, as the game drip-feeds other game elements such as homing missiles and mines into evermore complex areas. Then you hit a road block; the game wants you to jump, kick off a nearby wall, balance on a moving platform for just a second before using that momentum to shoot yourself up and over the missile that's been tracking you the entire time and back over to the... And you'll have died by now. A big ol' pile of stick-limbs blown apart either by the aforementioned missile, or by landing on a mine, or a random electric shockwave will have come in and had at your little pixel-hands. It doesn't matter if it was the second, fifth or 25th level that made you do the classic gamer-rage half-statement of "Well how am I meant to...!?" before dropping the pad. N+ is one of the most proficient platformers ever made, but man if it isn't custom designed to tear your psyche in half in the process - meaning only 4.44% of all users actually finished all 50 levels.
