Game & Watch: Manhole

[DSiWare] Move quickly and use your manhole cover to prevent the pedestrians from falling through the holes. Pedestrians appear from the left on the upper path and from the right on the bottom path. Earn a point every time a pedestrian walks safely over a covered manhole, or receive a mistake icon for every pedestrian who falls down an uncovered manhole. Receive three mistake icons and it's game over! [Nintendo]
