Stickman Swing Star

Stickman Swing Star is a one-button swinging game. Press and hold to latch onto the closest ring, rock back and forth to build speed, then release at the right instant to fly ahead. Get the timing wrong and an obstacle stops you; get it right and you sail over the finish line. Only the mouse is needed. Another launch-and-fly idea is Vex Try To Fly, and the front page lists more casual ideas.
