The Bitbag reviews, "Tetsuya Mizuguchi's next gaming journey has come to XBox Live Arcade. Mizguchi's prior exploits include many cult classics, including the iconic Rez (also bound for XBLA), with which E4 shares a few traits. Both games have a heavy basis in music, or might more correctly be described as expertly using music to substantiate and enhance the player's experience. E4's primary game mode actually integrates a rhythm element, though at a much simpler level than games like Boom Boom Rocket or dancing games."
