This is my "game" that is about being a square, picking up the yellow "blips" and avoiding the blue enemies. My problem is that the enemies appear before the if statement, even though they shouldn't. I don't know if blitting is the best way of doing it, but since I am a beginner I do not know, and it's been working well for me so far. I also want to cover up or remove the "ball" but can't find a way to do that, since blitting in an "if" statement does not work and covers it immidiately. If there is any help or tips you can come with I will gladly accept, as well as how to improve and/or cleaning up my code. Thanks in advance!
