This is an excelent podcast. The planet match game is the same as egg match in other games wich means it is not accessible at all. You can see stats but you cannot see anything else.
Nice podcast indeed. Have you contacted the developer to ask if the planet match game is ment not to be accessible? In the description of the app, it says the app is accessible with Voiceover and Talkback. So the Planet Match should be accessible as well. It would be great to get that confirmed by the developer.
