Before we begin, I'd like to address my hyperbolic title. You see, I'm actually pretty convinced that Cosmophony is proof that the Devil is real, and that he wants us to play rhythm games. That's not to say that it's a bad game, per se, but that it's fiendishly difficult and unforgiving. Teasing you in with a quick, easy tutorial and checkpoint-based Practice mode, it lulls you into a false sense of security before unleashing the unholy wrath of DJ Salaryman, the drum and bass artist who supplies the good, if frantic, soundtrack to your descent into creating new swear words.
