I absolutely adore this game; I've owned it for over a year and come back to it every few days or so! I find it so easy and fun to pick up for a quick game or two to fill time.
I'd say a bold claim, I love Tetris and this game easily tops the original Game Boy game; what with the added inclusion of the Kraken and the fact it has the full 20 lines, (like the NES version.)
Well worth the pricetag for the amount of enjoyment I've had from this game.
