Query: This game stinks unless you live by puzzle games.

I liked the original tetris. Not to complex, pretty addicting. I even liked bust a move. So with all the good reviews of this game, I thought I'd give it a spin. I did and regretted it immediately. This is way to complex to catch on in any similar fashion to tetris. Your grandma could play tetris or bust a move. She will never get this game.Bottom Line: Polarity blows this one out of the water on the DS. Will I keep it? Nope. Is it for kids? Nope. Too complex.
