It's a great game and I love it. I only have one issue though. I was having a huge issue with the what is the vocal range. In the game it said to sing your lowest note which you are comfortable with, which for me is around G3 if middle c is C4. But I can go as high as E6, and on lucky days F#6.
So what i'm trying to get at is if someone has a huge range then the notes for you to hit aren't very well represented in the game. Is there a way you can ask for the player to input the highest pitch they are comfortable singing as well? If so, when you calculate what note to hit can you just take the ratio of the distance between the notes shown one the screen to be more accurate for the person?
Thanks for making a great game!
