I uploaded a whole of code,I am sure that the problem is around "def score_display" I was doing the exact same thing what author did. But infortunately I got the error. At the beginning the code runs perfectly and when I fall and the function where I have mistaken should be fulfilled then the game breaks and gives this error. Thanks (so sorry about grammar)

The problem is in update_score where you return a None when score <= high_score. Just dedent that return statement.
def update_score(score, high_score):
if score > high_score:
high_score = score
return high_score
