The game was created using Unity 3D. The maze itself was built in Blender 2.61 using a textured cube, creating a 16x16 array then cutting out faces for the maze. The maze was then exported using the fbx plugin - took most of the time!
The game movement script is essentially the one that Gabriel Williams describes in his "Unity: Creating a Game in 30mins" tutorial.
Special thanks also to Patrick Boelens for helping me get my head around the scripting process - well at least partially ;-)
You can try the game out here (I know it is not perfect - but it is my first attempt) :

Use the arrow keys to move as in Gabriel Williams tutorial.
TY to all at Blender and Unity Cookie.
