Rovio Entertainment is a complete ripoff! The game in specific question is Angry Birds Transformers; although I have experienced these same issues with other Angry Birds games.The game has become deliberately more difficult to operate in that Rovio constantly removes free features. Leveling up is next to impossible because of everything changing to a subscription like design when its advertised as a free to play game. There are numerous glitches, especially when supposed upgrades occur. Support is a lie as well because when you report the issue, Rovio refuses to acknowledge the issue, refuses to refund cash or replace lost data/ items/materials. If they even answer you, their response is consistently the same; it's the players fault and they know that's very frustrating but there's nothing they can do. Rovio is a scam!
