There's no menu screen, but you did add a score screen and the game doesn't start on it's own, unless I pressed spacebar. Also I'm surprised how you managed to make a boxing game with such small screen size i.e. I mean the collision detection gets pretty challenging when screen size is low. But you still made a cool game past the challenge, I like the life bar and the characters you designed and would love to see this further developed!

I checked it again it is much better than before, good job!
