I'm stuck on spotting the differences. I can't do a straight pixel-for-pixel comparison, because of scaling artifacts or something like that. So for a human eye, the differences are obvious, and I don't want to bring in a huge image processing library like openCV when I don't know what the hell I'm doing.

I'm moving on to other things and will revisit this later.
Created MazePlayer. I am able to parse the test maze into a boolean array.
