It's not a bad start for a blind person playable game. I do suggest adding in keyboard controls at some point though if you plan on developing this more as a lot of the blind people (and I mean those with no usable sight like myself and not those who can see somewhat) will likely use the keyboard more. The only reason I could play this with the mouse commands is due to a screen reader keystroke that activates the mouse and I'm not sure it worked all that well.
I did have trouble figuring out when to actually run from the hunters too. It got very confusing. The voice parts were great though.
I mention this all as constructive criticism and not to insult you here. These are just my initial thoughts after trying out your game.
