This game is incredibly charming and very fun. If you've played the first DS Bust-A-Move type game, then you'll be familiar with the format. This game improves of the cutesy cartoony graphics, with great character sprites. Story mode is excellent, with imaginative (within the constraints of a bubble puzzle) boss fights, a shop feature and points allows you to customise the game, including how the bubbles appear (e.g., simple, fruit, gems) and the arrow.
All in all a great package, at a good price.
