Turnabout

You run through a field of posts joined by green doors, chased by whirligigs. Walk into a door to swing it a quarter turn round the post at its far end; it swings only if the space it sweeps through is empty. Whirligigs cannot move doors, so swing the doors to shut one in: a whirligig that cannot move at all for a moment breaks up, worth 50 points, though two or more shut in together survive. Clear every whirligig to finish the level and score the time left on the bonus timer plus a level bonus; when that timer runs out, everyone speeds up. A touch from a whirligig costs a life. Each level adds a whirligig, up to seven, and from level 7 they get faster. Every second level cleared gives an extra life or 250 points.

Controls: Use joystick 1 or 2. The stick runs up, down, left and right; a button starts each round and works the menus.
