Description

JSGrappler - You are a little pixel armed with a grapple cable, click to shoot it at the platforms, catch a platform to fling yourself higher. If you fall below the bottom (even while grappled-(feature :P)) you die. Just refresh to try again. Updated - You dont have to refresh when you die, and your high score is saved (until you leave the page) Can you get above the coveted 5000 mark?
