The rewards in the Mighty Eagle Mountain are rigged. Only 5 gems on floors 1-4 and 6-9 though there is 20 on floor 5.
They wont "fix" it. Rovio just nerfed it on purpose about 4 weeks ago to try & get people to buy diamonds. They also made it a much lower chance of actually opening a gem door.
Or else what? Sadly, if you think they actually care about whether or not you quite playing, you are mistaken...
They responded: Sorry to hear that, we appreciate your feedback and we forwarded your ideas to the game team. All I got and I expect nothing more from them
?? I'm not excusing Rovio's greedy behavior at all. Just saying that they don't actually care about the players & especially not 1 person who quits. All they care about is trying to extract some $$ before the game dies. Also, this is not behavior unique to Rovio at all...
