Boom Boom Rocket has the gameplay down to a great ballance, but a lack of content brings the package down a bit.
The game features 3 difficulty's for the main song mode and for the Endurance mode and playing through each difficulty adds some legs to the game.
The main problem with Boom Boom Rocket is that the 10 tracks included don't give enough replay value to the game. The multiple difficulty's and Endurance mode are nice additions that do add to the game time though.
The gameplay is great, but a little more substance would have made Boom Boom Rocket a better Package.
