Here is IGNs review of it:

I just picked this up today, and all I can say is BUY IT! Its a great little puzzle game for the GBA that came out of nowhere. I am having a blast playing it, and best of all its only $15! So you can't go wrong. There are plenty of modes, and something like 270+ puzzles. Its not a Tetris or Tetris Attack type puzzle game, you actually solve a puzzle. Its great fun.
