I love Bust-a-Move on Playstation, so this was a must-buy for me as soon as I bought my DS. Though I must say, I was a little bit disappointed in comparison to the Playstation, but the game itself is excellent.
The game itself is the same as on Playstation, and for any gamer, I would definitely recommend it. It's such a fun game, and simple too. There are different challenges on the game, including a Puzzle, Endless and Computer mode, as well as multiplayer if that suits you.
However, I just don't really think that this is the type of game for a DS. The two screens make it quite awkward to play the game efficiently as aiming it therefore difficult. I was thankful that you don't have to use the stylus, though if you wish too, you aim by using a slingshot method, but it's really quite difficult!
So overall, the game is brilliant, but I'd recommend buying the Playstation version, more than the DS version.
