Hold mouse button down to accelerate. Point the mouse so that you fly through the rings. The more rings you go through, the faster you are, but the more fuel you use up. The higher the difficulty, the faster fuel is burned up and the rings will move for a difficulty larger than 0. *Race* - You have 60/(difficulty+1) seconds to fly through as many rings as possible, each ring giving +1 second. If you miss a ring, 2 seconds are deducted from time. *Practice* - Flying without worry as long as you don't fly out of bounds.
