hold down left click to launch your grapple use WSAD or ARROW KEYS to move COLLECT THE POWER GEMS GRAPPLING TUTOURIAL: Swinging~ Grapple onto something above you, don't hit your head, as hitting your head causes to get you stuck, then continually press the A and D keys to build up momentum, and then you're swinging :) It's a very stretchy elastic swing... Catapult~ Well, pretty much the only way to get over the tall stuff. From the floor, grapple onto the top of tall things and you'll fly onto them, be sure to use the movement keys for extra control. Carousel~ When swinging from the floating blocks, try swing high enough you so can continually swing around it 360.
