I swear, this game is just pure unadulterated digital crack, even stronger than the first one. It's got cool music, exploding gems, lightning, 4 different variants to play, talks to you and looks absolutely stunning. All you have to do is see someone play it and you're addicted. Those of you with addictive personalities would probably be better off not even touching this game.
It's big, taking up 1.5 MB of space on my PDA and another 755 kB if you install the music file. If you've got the space, it's definitely worth a try (if you dare).
