Question about Sprite Collisions

So what you’re saying is that the only way to do it is to make each piece of wall a separate sprite? Wow that would make it a lot more difficult to add different mazes. I thought that by making the maze walls one sprite, it was still a sprite (it is not part of the background). That doesn’t make a lot of sense to me in how the program is set up, but thank you so much for the help.
