So have installed the game crafting kingdom, after reading the write-up and the encouraging statement that the game is fully accessible with voiceover. However, it appears that the developers are aware that there is in fact an issue with accessibility as they have made a suggestion for the possibility that accessibility mode is not automatically generated. However, the suggestion made is to three finger triple tap the screen, which every voiceover user knows is actually the gesture to toggle screen curtain on and off and is therefore not a workable solution to the unavailability of accessibility mode.
So, it happened that when I installed the game accessibility mode hasn't been automatically enabled. And as such there is no workaround. Have removed and reinstalled the game to see if that changes things but that hasn't made a difference.
It therefore appears that we have a game which is accessible to some, but not to all, with no means of making that happen presumably until future updates if those are forthcoming.
It is heartening when developers give some thought to accessibility. But thoroughly disheartening when it appears this was only a half-hearted thought process. Clearly the developers have little understanding of the workings of voiceover given their workaround suggestion.
Have given the app a one star review as a result.
