Wonderful, but issues with Game Centre Achievements.

I love this game. After I reached max level in Transistor, I determined to try this one. It didnt fail me, absolutely. It wasnt the style that kept me fascinated in Transistor, to be honest. But still unique, cute, and delicate. The plots are great, no doubt on that. It has the same kind of stunning ending as Transistor. I wont talk about other merits like music and gameplay here. The only issue that I encountered was that I cannot unlock the 6 achievements in Game Centre No matter what I try. 2 from Kids Dream, 2 from Survivors Dream and 2 from Singers Dream. Stranger still, its possible to unlock the 2 achievements with all 10 shrine idols invoked. I wonder if I did something wrong in the process or its simply a bug with game centre. I have seen the same issue raised on some forums. Since the issue is with game centre and by no means affect the game, 5 stars. But!! pls fix this if you can. Thanks!
