Problem in 1.2.2 version OK, we found the problem. If the language of the device is NOT english, spanish or french (which are supported), the app won't start. So, the workaround to play the game while the update is approved is to switch your device to English. We have submitted an update and asked for an Expedited App Review to Apple. Sorry guys
Thanks for the help and I've now hot the app running. Just played the tutorial, it was a perfect introduction to the controls, didn't bombard you with everything at once, I'm looking forward to playing this a bit more.
Good news. Apple accepted our expedited review request. Version 1.2.5 has just been approved and should be available within the next few hours. Thanks!
