Don't even bother; More than half the missions are taken from the online PSA missions and can be played free.

Plain and simple, this game is horrible. Only 4 of the ten missions avalable (Yeah, 10. The last game had 13. Not to mention the last game also had sidequests, which were taken out this time around.) are exclusive to this game. 6 of them can be played on the online Club Penguin for free, and you have to beat these missions that, chances are, you already beat a million times, to get to 3 of the new ones. The new missions don't really make you think much either. It's often pretty straightforward what to do and how to do it. Not to mention they took away the ability to roam the island and buy clotheing from the first game. You now get a very limited selection of clotheing, around 10 items all together, for beating missions. The whole game feels like the developers took some stuff they already made, slapped it together, added a very small amount of new content, and tried to make a quick buck off of it.
