Could have been a 5 star

If it werent for the divisive placement of the "buy guitar" button where the user input is, I would have given it full marks. Every time i miss the answer button by a micron i am asked if i want ti buy a guitar for $2.99. I am a guitarist I have no interest in buying ukelele or mandolins to learn. Put that stupid button in another menu.
