Music, a new spedometer, and a minimap with little arrows pointing the way to go. w00t!
Race around the track as C4L or Delta! C4L is the easy car, so get used to him first. Up to accellerate, Left and right to rotate, Space to brake, Down to reverse. I give full credit to the car engine to that Advanced Car Movement tutorial. Get as many laps as you can in 150 Seconds!
