Pointer game

I have seen this labyrinths that have to be navigated through with the mouse at Alex Frank's dontclick.it. It is essentially the very simple idea that you should move the mouse pointer along a labyrinth without touching the walls.

Today I've stumbled upon a similar white label game that additionally features further game elements, such as moving obstacles and shooting. Not that it brings the game so much further, but it is a good illustration how particular game objects could hugely change the entire gameplay. There's also another game that uses a similar idea, but it introduces complication on the mouse pointer, something they call yoyo ball. I definitely find the first one more interesting.
