Hold to fire the hook and swing like a pendulum. Let go at the top of the arc to fly to the next anchor — time it right or fall.
Grapple Swing is a free hard physics game online: hold to grapple onto anchor points ahead, build momentum swinging like a pendulum, then release at exactly the right instant to sail forward and catch the next hook. Anchors get trickier to reach as you go. Miss the timing and gravity takes you down. Simple one-button rule, punishing precision.
