Cool - you've used fixed mirrors though? The versions of this game I've played had the rotation of the mirror as part of the puzzle complexity.
So you have a selection of mirrors in a toolbox that point at varying 90 degree steps that you drag onto the screen in some kind of maze - then when you press 'go' the laser draws its way across the screen to the goal. There'll also be fixed mirrors on the screen that you have to hit with the laser to complete the level.
