Colored platforms can only be used by people of that hue. When falling, hold A or D against the wall to wall slide, slowing you down so you can see what's coming below. When you're blue, you can create a temporary ice block with the Spacebar. When yellow, you can press S to become insubstantial. Nothing can touch you, but you can't walk; you can only move by slippery floors or treadmills. You can use the flamethrower ability while red to eliminate hostile creatures.
