N++

Gameplay consists of platform-style jumping, dodging, climbing and rebounding from walls, collecting gold pieces to extend the time allotted to complete each level. Momentum serves a big role in the player movement, with the jump height being dependent on the player speed and the angle of the platform. To complete a level, the player must navigate towards the exit button and arrive at the exit while avoiding a myriad of enemies and obstacles along the way. Levels are grouped in "episodes", each containing five levels.

A level editor is available, along with the ability to play online levels created and uploaded by other players.

Review aggregator website Metacritic gives N++ an average score of 82/100 for the PS4 version, 88/100 for the Xbox One version and 90/100 for the PC version. GameSpot awarded it a score of 8 out of 10, saying "N++ may represent an 'if it ain't broke, don't fix it' sort of expansion, but the exhilaration that it continues to offer speaks to the idea that it may have been perfect to begin with."

PC Gamer's Shaun Prescott gave the PC version of the game a 92/100 rating, describing the game as "a masterful distillation of classic action-platforming gameplay, doling out tension and elation in equal measure."
