In my opinion, this is probably the best game for the PSP at this given time. I love the puzzle game genre, but even if I didn't, I could still see this game being one I continue to play years from now.

The music and the artwork, or skins as we in the know call them, are absolutely fantastic, which is what one would expect from the creator of Rez.

The premise is easy enough, take a 2x2 cube of different colours, rotate it and drop it to make a 2x2 cube of the same colour from other pieces which will be cleared by the timeline. When the pieces don't line up, rather than tetris-style freezing in place, they break apart with that which is not supported underneith falling. The timeline is a bar that moves across the screen to the beat of the music. Also, cubes can overlap, which means massive combos. IF you clear more than 4 cubes on any given sweep of the timeline, you will recieve that number in a multiplier bonus on the next sweep, so take good care to not give in to relaxing once you've cleared half your screen..
