A great puzzle game probably the best game on the PSP
Gameplay- The gameplay is simple and intuitive. its kinda like tetris, but better. you make rectanges and squares of the same colors and a "timeline" will blast them off the screen. This timeline is an amazing idea. You can race the timeline, or fight it. This timeline will get very important as you play because certain maps will slow it down or speed it up.
Graphics- The graphics are great. Th colors or bight and sharp with interesting backgrouds.
Sound- the sound is great and interactive. moves certains ways or rotacting will make sounds and its pretty neat. the music tracks rock and never get annoying, and they feel prefect for the game.
Value- The game has a long single play, puzzle mode, and VS.mode, puzzle mode is really interesting and the VS. mode is fun too. In the Vs. mode again the computer you can get more avatars and background as your can with the single player. Vs. mode can always with used in AD HOC with other people.
