Probably not everyone will be able to figure out the error, even those who have python, they probably won't have "pygame". I installed it, though after a couple of minutes an error flies

I tested my game myself and I haven't found any bugs. When you reach 100 score you reach a boss battle, do you know exactly when this error came or what may have caused it? Also I am aware of that having python and pygame installed isn't very common, but I had issues with creating an executable of the game so I just went with the .py file.
