This game keeps you coming back for more. The levels are fun, varied and challenging, so you "have to do one more" just to see what happens next.

I am particularly taken with the instant-reaction gameplay. You never have wait for the pieces to move before you can make your next move - very cool! When you've tried a game that is as responsive as this one is, a lot of other games suddenly seem irritatingly slow-to-react.

The soundtrack/music is pleasant, almost calming, and creates a good underwater feeling. The sound effects also stay with the underwater theme. At no time are the sounds or soundtrack irritating - which is a huge bonus because of the totally addictive nature of this game (I found myself playing for a lot longer than I expected)

Highly recommended!
