Yesterdays update crashes on iOS at startup. A fixed update has been submitted and should be available within 2 days. Apologies for that. No doubt I'll acquire a few one star reviews for the mistake.
This is not a case of me not testing the game properly. It runs fine locally, only the App Store version crashed. Apparently the 2 day wait period for the App to be reviewed by Apple does not include them even checking that it starts up!
