Just found a charming little timewaster. It's a pixel-art game called Gravity Hook. The aim is to climb as high as you can up the screen by attaching your little character's grappling hook to a series of floating mines and using the momentum to fling yourself ever higher. careful though as attaching to a mine will arm it, and if you get too close... BOOM! It has a real one-more-go factor and the desire to better your previous high score is powerful. Mine currently stands at 730m. Can you do better?
