I've been trying to make the main menu with my game. But every time I would run it and 'start' the game. it would give me this error
line 303, in redrawGameWindow text = font.render('Score: ' + str(score), 1, (0, 0, 0)) NameError: free variable 'score' referenced before assignment in enclosing scope
Which then I try to fix but couldn't.
Here's the full code:

Sorry if it's too long. But the def is more in the top/bottom. I'm just a beginner wanting to learn more.
