Ah, thank you for the reply!
Just a couple of follow on questions then if you have the time... :)
You mentioned controller support but is their any keyboard support? Most severely blind people do not own controllers, as most games on consoles are not accessible, most of us exclusively use the keyboard, with some mouse users sprinkled throughout.
Also, does your game include any "alt text" labels on important images? Are visual indicators for control status' also shown in text? Both of those things are very important for a truly blind accessible game.
