[PyGame] My program is very laggy

Thank you for the new code.
Attempted to run the code, and cannot as the images
Background.png and Door.png were not provided.

I'd like to run through the profiler.
This is also something that you can do yourself, see: https://docs.python.org/3/library/profile.html

If you provide the images, I'll take a look at what you have to see if I can spot bottlenecks
