In my pygame platformer, when I jump it sometimes randomly jumps more than double of the normal jump. I've been trying to understand why this happens but I really don't know. I've been testing it and it appears to be completely random. It does it when I jump while moving, when I jump standing still BUT, surprisingly, it doesn't do it when holding down the jump key instead of clicking each time I jump. Here's the code

Let me know if you have any questions
