Angry Birds Friends APK 13.1.0

5 stars: Been playing this game for years. Recently been dealing with lengthy advertisements, Double ads which makes the game boring and causes you to loose interest. Earth shaking changed to useless. But it's the too much & too many lengthy ads that kills it.
4 stars: The game is great, I love Angry Birds, but my only complaint is that you have to connect to a FACEBOOK account to save your data. I want to save my data, why not also allowing saving it with the Reds Club or whatever it's called? Or add the option to use a Google account? I don't think it should be confined to Facebook, cause I'm not about to make an account for it just to save data on Angry Birds.
3 stars: I've enjoyed this game for a long time, but lately, the Star Cup is impossible. It used to be an easy way to earn a few coins, but now you can't; as soon as you launch your last bird, suddenly, your opponent gets a massive jump in points. If the game is doing this purposely to encourage in-game purchases, that's pretty shady. If it's a glitch, it needs repairing.
3 stars: I used to love this game. It had a nice balance of levels. Skill mattered, and with persistence levels could be completed with 3 stars without power-ups. Now it feels like almost every level requires power-ups, and they are much harder to earn. It's a clear money grab by the developer who want you to spend in order to advance. It's frustrating and disappointing. I'm not ready to uninstall, but I probably will if this carries on.
