The simple gameplay make it easy for anyone to pick up and play, the amount of levels and variation of the types of birds you can use keep you playing until your batteries run out. The Nice looking graphics and basic controls are also quite good.
The Bad Points
The difficulty of some of the levels further on in the game really do start to get on your nerves after trying to a the level for the tenth time. The Annoying theme tune and bird noises really do drive you insane!!
I recommend playing with the sound off or playing your own music in the backround.
But Still its quite addictive and well worth having a look at or trying the lite version for free. but be warned time will fly while playing on it.
