Well, I got my copy in today and played it some tonight.
While it is a *very* well put together game and really adds a neat twist to the puzzle game genre, at the core of the game, it's Bejeweled.
Personally, I don't think that's a bad thing, but I know there's a *lot* of people out there who very much dislike Bejeweled and thus, it could be a bad thing if you're considering this purchase.
So, anywhoo, it's Bejeweled. Except that you and your computer-controlled opponent take turns making moves. When you (or your opponent) matches three or more symbols in a row, something happens. Depending on the symbol, you may cause damage to your opponent, you may collect cash or exp points or you'll likely collect mana. Once you've collected enough mana during around, you'll be able to cast spells. The effects of these spells vary and do handy things like cause your opponent to miss a turn or two or can heal some of your hit points.
What this game badly needs though is Wi-Fi Connection. Seriously. At this point, I don't think there's *any* reason to release a puzzle game without some kind of basic online battle mode. Even more so, when you consider the format of this game. Heck, I'd almost be happy with a single-cart download version of the game. The two-player mode does exist, but since this game seems to be a little bit harder to find, I'll probably never find another person with it.

It's a good game though. Although it doesn't beat the $1.50 I paid for Zoo Keeper DS, since most of you won't run into a deal that good, if you're wanting Bejeweled that you can take with you on the go and for whatever reason haven't downloaded *that* on your cell phone, you can't go wrong with this one. Additionally, if you love to waste hours playing Bejeweled, this game will give you a bit of a new twist on your old favorite.
In conclusion, I rate this game an
i/10.
