Very entertaining game! If you like music, get this game. Includes a fast paced puzzle game and patternizer/sequencer.
As for the actual gameplay you have to create a line (like tetris) out of different pieces. When you get a line you must add more lines to create a combo that attacks the opponent. The more lines, the greater the attack. Each character has there own special combo like raising the opponent's blocks towards the top where it is hard to move them back down. You must keep the blocks away from the top of the screen with your stylus because with time the blocks are shifted upwards.
Some of the characters are crazy for example, a robot-chicken hacker, a rather fruity pig, a techno penguin, guitar-flute swinging country kid, high as a kite fox, and a rapping bulldog. Yeah. Anyways, each character possesses a 'sound set' such as hip-hop, techno, pop, country, reggae, or house that is played while you play the main game. All 2-D graphics here, nothing stretching the ds limitations. Great creative artwork however with highly detailed characters. Very colorful and fun.
Great replay value to earn unlockables such as sound sets for the sound box, achieve high scores, or get owned by the computer. The sound box is great for just making beats for fun and is worth coming back for.
Great hidden gem here. If you like music, buy this game. Pure fun and highly addictive.
