[26] GameSpot gave it a score of 7 out of 10 and said much of it was "the stuff of childhood dreams", despite some spots that were "rough around the edges", and that "the exhilaration of flight, the feeling of power, and, perhaps most importantly, the sense of personal responsibility for the planet, has never been captured quite like this before.

"[28] Nintendo Life and Push Square gave the game six and five stars, respectively, concluding that it was "an indie hit that wows with its sheer scale and the breadth of its ambition...this superhero simulator struggles to maintain the impressive impact of its first hour, or live up to the lofty heights of those dangerously high ambitions.
