Heres your fix:

This is a quirky little word game. Really enjoying it. But I see others complaining that it wont load. Heres the issue, developers:

Youre waiting for Game Center to initialize before you allow the game to start. Im not sure what caused this, but Game Center on iOS 9.0 often takes MINUTES to load. Ridiculously long. And then (on my phone, at least) it causes a game to freeze for a couple seconds when it finally does load.

Awful. Apple really screwed it up. But do your users a favor: dont hold up the game waiting for Game Center. Most other games proceed just fine without it.
