The colors hurt the eyes and the content is not worth the 1200 points.
Also, the color screen hurts the eyes. Seriously, do they expect players to stare at a screen for hours on end watching blocks that are colored bright neon blue and bright neon pink, and then to proceed to color changes of bright shining white and bright orange and other similar color schemes? Everything is just too bright, I'd spoil my eyes and my TV screen!
Where's the signature Lumines music from Mondo Grosso and Nobuchika? Sadly they have been left out of this game.
What a total disappointment this game is... and it's not even a full game, it's a demo that's priced even more expensive than other Xbox Live Arcade games. Save your money, spend it on other more deserving games.
