It may have a few problems but still has a lot to offer, for anyone who hasn't played it on mobile phones.
Gameplay: If you have played it on mobiles or on an Ipad, you'll notice that you won't be using the touch screen to fire your bird. However instead you are using the analog stick to aim how high or low you want to fire; and tapping or pressing X to release your bird from slingshot. There are several different types of birds you'll use throughout each of the levels from a Red bird which is the basic and standard bird; there are also Blue birds which can separate into three birds if you tap X at any time. And there are also Black birds which can explode and cause a lot of damage, and there are also White birds where they can drop egg bombs from above.
Each level starts with the number, types, and order of birds pre-determined. If all of the Green-Pigs have been defeated before you use the last bird, you would have to start the level again. Each of the pigs you'll defeat you will earn points and also smashing up stuff can earn you points too. Completing each level, players receive one, two, or three stars, depending on the score received. Players may re-attempt unlocked levels as many times as they wish in order to successfully complete them or to earn additional points and/or stars.
Graphics and Sound: Graphics do look identical to the mobile phone version pretty and colourful, which still does a great job. But however there a few issues during gameplay where everything slows down making hard and frustrating to see if aimed and fired your bird correctly. It's also the same when if you hit any objects or if they are all piled up it slows down and you're wondering if you've got rid of the pigs or not.
There isn't really much to say more about its graphics and problems it has for it, the sounding is about the same the mobile phone version. The bird and sounds and hearing the same music can be a little annoying but you could also mute the sounding if you wish.
Overall: It might not be the best version of Angry Birds on the PlayStation in general but still has a lot to offer for anyone who hasn't played Angry Birds what so ever.
There are around 200 levels throughout the game and each of the levels will offer you an easy puzzle or a hard one, but however you could also say that it's also the only decent PlayStation minis game worth checking out and only will take 18MB on your PSP or PS3.
