So I'm trying to recreate a PacMan game using pygame. So far my code works smoothly, but I wanted to know if I can format a background image based on the grid I draw like scale it to match the maze made of rectangles. I also have an issue where the character speeds up when I hold down the arrow key, is there any way to make him move in constant speed even when I hold down the arrow key? Thanks
