5 stars: Playing all of the games since 2009; enjoy ABFriends bc l can either play solo or if I'm in the mood, against other opponents. Love that there's no life limit bc l can practice before l play a human opponent. The levels are random difficulty & each one requires different physics & bird abilities. The boosters help a lot when you learn how & when to use them.
5 stars: This game is really fun, and it's not so easy that's boring, and not so complicated that it takes a long time to complete every level. Speaking of which, there are many levels and every one is different. I really like that you can buy upgrades without using actual money - just using the coins that you earn easily from playing the game. You should really consider downloading it.
4 stars: I really like this game, the physics are good and it is really impressive that they come up with new levels every week although I do have a couple complains that put this down a single star 1. You can't save any levels so if there is a level that you really like then it is gone forever 2. I wish there was an option to go in a tournament where power-ups are disabled.
3 stars: Loved this app when started to play. I now get to a certain level and the next time I log in to play it starts me back at the beginning. Can't save progress on Facebook, so can't get my progress level back. Very frustrating. Can't contact you unless you are rating game to get help. Same thing used to happen on angry birds 2 so I no longer ...
