There are three power-ups that turn you into a wisp temporairly. They are the indigo asteroid, yellow drill, and cyan laser. The indigo asteroid destroys everything it touches, and also has a large magnet ability. It continuously floats downward, then floats back up when you tap. Use it to destroy as much of the landscape and enemies as possible. Sometimes you will uncover hidden treasure from the ground. The yellow drill automatically burrows underground and continues along this trajectory. It pops aboveground when you tap. Time your taps when you see arches of gems or enemies. The cyan laser shoots forward through the sky automatically. When you tap, all gems or rings on the screen will be pulled into him automatically. Tap quickly to collect as many items as possible.
