This update involves two fixes to the movement jittering when colliding with the walls of the maze (see comments in my previous posting), and a couple of additions.
First the “spinning” when colliding with a wall. I modified the “Player” constraints so that rotation is frozen on all axes. The axes are unfrozen when you want to turn (right/left arrow keys) then refrozen when keys are not pressed.
The issue of “running through wall face” was corrected by mounting the camera on an “empty” with a box collider, and moving the camera back from the center of the empty.
The additions are “doors” which involved learning about triggers and how to rotate at the “hinge” area of the door and not at its centre. And as a little fanciness I added audio when the door opens (creaky sound) which was another learning experience. (“O” key to open)
The maze and door built in Blender 2.61
New version can be played here:
TY to Gabriel and Patrick again.

If I may be so kind as to suggest slowing down your character by slowing speed or multiplying speed by Time.deltaTime otherwise great improvement from last version
“suggest slowing down your character by slowing speed”
Sure Southern – there is a speed factor that can be changed. I’m so used to the maze now I just race through it

Still like walking on ice
But good work.
Ty Markusb1976. I think the problem is the speed setting as SouthernRebel also suggests. As I said, I tend not to notice it. But I will be looking for a fix in the next update – maybe a speed control.
That will go along with “Open and “Locked” doors and the ability to view objects that might be found in the maze.
Hopefully Update #2 within a week.
TY to both you and SouthernRebel for the feed back

And another thing is that your walls are to tight together. In my opinion
You shoud expand them, makes it easier to walk through your maze
