“Maybe N++ needs to be consumed in short jaunts—pop in for a quick platforming fix and hop out when your eyes start to bleed. The core of it, after all, is trimmed to near perfection. Its sprawl, though, invites long play sessions and the short individual stages fuel a dangerous “just one more, just one more” fervor. A quick jaunt can easily turn into twitchy marathon, and before you know it, you’re anxious and grimy and feeling like you woke up somewhere disconcerting after a long bender. Looking at the progress page after a session, that silly 3,000 percent completion number feels less like a friendly joke and more like a snarky challenge: “How much can you handle?” N++ seems to be asking. It might not be a challenge you want to meet.”
