I absolutely love this game. I'm also totally blind and I have no trouble at all with playing the game. Maybe it's something I'm not doing correctly, but when I donated, I confirmed, then the apple store wanted me to confirm again. It ended up charging me multiple times. However, if my small donations will help to keep this game updated, I'm not worried about it. It's more than worth it. The quiz thing is pretty frustrating, but that has nothing to do with errors or problems. It's just a challenge that I'll have to figure out. I get that far in to the game and then give her the wrong answers. LOL It's an awesome game and the suspense is killing me. Great job!
I'm happy to hear that you are enjoying the game :)
But I'm sorry to hear that you got charged twice! Even though it's nice with the extra contribution, it's not fair.
If you can see that the money has actually been charged twice from your account, you should send a complaint to apple about it.
Anyways, I hope you enjoy the rest of the game! Can't wait to make more for you :)
