Space of course features two major innovations: Gravity Wells and Zero Gravity. In Zero-G, the birds seem to only fly in a straight line. Hitting a dynamite box sends debris flying in almost every way possible, while nudging a green swine sends it floating through space. Most of the stages in Angry Birds Space feature tiny moons that have their own gravitational pull that will suck in birds and pigs/objects alike. This can pose a challenge when obstacles are in the way, but as long as you're an adaptive player you can use the gravity effect to your advantage to hit hard-to-reach pigs or dynamite. In Angry Birds Space sometimes you'll even has to sling birds around a planet to attack from the back.
Rovio's newest sequel is the first to actually feel like a sequel as sad as that sounds. Angry Birds Space adds new elements to the game right from the start and that's always a plus, and with the increase in difficultly later in the game with more planet gravitations it's a challenge and with 60+ stages and more coming soon it's almost too much to ask for. Not to mention the two new birds introduced into the game which keeps the stages fun and fresh. A square like ice bird can be detonated like the black bird to freeze any blocks or near by pigs to set up the little blue bird for a clean shot. The Yellow dive-bombing bird has also had a little tweak in color and use, instead of doing a straight dive you can now send him anywhere on the mission just by tapping the target, this includes going backwards. Angry Bird Space adds a new style of Physics to the game and it does kinda bring down the experience down a little. you can fling the same bird five times and have totally different results which can be very frustrating when you want to snipe the last pig on a level.
Should you buy it?
Angry Birds Space is the kick in the pants Rovio needed. Everyone was burnt out on the same birds flinging and flying concept. Angry Birds Space however brings a whole different idea to the table, it's action filled and you need a bit of skill combined with luck in order to complete missions and with 60+ levels it's going to take you a long time to beat, but an entire third chapter with 30 more levels is only available via a $.99 purchase (in my opinion I wouldn't get it). Additionally, the "Mighty Eagle" isn't as Mighty anymore. The level-cleaing bird used to be a one-time purchase, but now can only be purchase as a consumable aka you can only use it so many times*. Each 20 uses of this last resort now costs player an additional $.99 bummer...
