I used to play a version of this game on my old gameboy when I was younger and loved it.
This one is pretty much the same, its a simple game but very addictive.
I wish they would update it though, give us the option to change the colors, the background, add sounds as well as an auto destruct button like another reviewer said, I too got stuck between lines and had to start a new game.
