GamingUnion: "The shoot-'em-up genre, otherwise more commonly know as the "bullet hell" genre by its fans, has been mostly relegated to PC releases, muted Xbox 360 releases and mobile devices, with only a sliver of the games actually skipping over the ocean to Western territories. With the videogames industry focusing on trying to appeal to everybody at once, the time-tested genre hasn't ventured out too much to appeal to anyone besides its fans." 8/10
