created the maze walls and collision detection

the hardest part was creating a maze with a solution. I realized I didn't know how to do that and had to google how to create a maze.
Once I had a maze generator, I was unsure of whether there was a solution to it. Figuring that out took some time. Then I changed the look to be more digestible. I chose a maze game because I thought it would be simple, but it didn't feel simple.
