Grappling may seem hard, but it is easy! All you have to do is jump, click SHIFT if a block is above you, and you will see a green laser (which is your grappling device). Use the arrows (up and down) to get csplode to the block (up) and farther away from the block (down). Use the arrows (left and right) to move left and right. Simple! Good luck!!! =)
