The songs in the game are fairly limited; there are only ten of them, but there is a degree of re-playability. Each track is based around a piece of classical music with an upbeat synth sound moulded around it in a ska, funk or techno style. This makes all the tracks recognisable; most people will know the 1812 or William Tell Overture, and anyone familiar with Bugs Bunny and Elmer Fudd will know the Ride of the Valkyries. This melding of styles is tastefully done, and the familiarity of the music really helps the player approach and learn the nature of the game.

As the song progresses the screen pans around a 3D cityscape, as if hitched to a helicopter on a joyride amongst the skyscrapers of New York. As fireworks explode due to good timing, the player is treated to different patterns from butterflies to dragons appearing in glittering, shimmering lights; there are some wonderful, if simplistic visuals.

None of this is random, so learning patterns and hitting with 100% accuracy is the key to high scores. The longer the stage goes on without the player missing a firework, the higher the multiplier. The closer the button-hit to the line, the higher the points awarded. Once in a level, a super-multiplier can be activated to boost scores to 16x, albeit for a limited amount of time, making the fireworks ultra-impressive; these are best saved for certain sections when there are a lot of arrows on screen. Once the round is over the player is graded based on the longest chain, accuracy and number of misses.

With three difficulty levels, the game is approachable from newbie to expert skill. For most people, the easy difficulty won't present a massive challenge and A-star grades should be achievable on most if not all tracks. Things start to pick up pace a little on medium, the game occasionally throwing dual button presses at the player. By the hardest mode, arrows fly up the screen at an alarming rate, and require a great deal of dexterity.

To avoid being a scrooge with game types, an endurance mode allows a song to be played on any of the three difficulty levels on a loop. Sneakily, the next cycle increases the speed by a margin, and by the time the third replay arrives things are really shifting. There are two achievements relating to this mode, and will definitely take a bit of practice to acquire, especially at the highest challenge.

XBLA’s Boom Boom Rocket is another excellent and approachable leaderboard-chasing romp through colourfully lit cityscapes with an upbeat tempo soundtrack. Though it's perhaps a little short-lived due to the limited tracks currently available, it's a lot of fun while it lasts.
