maze game

Hello. I was recommended this forum by a friend elsewhere.

I have a project to do involving a maze. I'm currently having a problem.

I'm trying to get the maze walls to appear, but as they are, they dissapear as soon as I try to move the circle which will eventually become the avatar.

If anyone wants to have a look, I have the project zipped called MAZE. As it stands, it compiles correctly and displays a small screen with the circle, plus the wall images. But when you press w,s,a,d to move the circle, they vanish.

Could anyone offer assitance?

BTW I deleted the debug folder, so you'll have to recompile. It uses GLUT for the graphics work.
