From Oz,
"Typically, I get into a shooter, jack the difficulty up at least one over "standard," and go to town. With Nanostray, having heard it was fairly challenging, I started at "normal." It was still pretty darn impressive. On normal difficulty, it very much strikes me as a memorization game; one where things are kinda crazy when you're playing a level for the first time, and far more reasonable once you know vaguely where the enemies are going to be coming from and can "lead" your reactions accordingly. This is especially important because many of the levels in Nanostray 2 have "maze" aspects to them, and players are asked to fly in tight quarters or through timed hazard zones. This means that the dangers are not just Bogey-based, they're equally environmental."
