Use the keys to control the cars. If you touch green you'll have to start again. If you go faster you'll have a better time, but it makes the car harder to control. Red car: Left and right to change direction, B and M to accelerate/decelerate Blue car: Q and E to change direction, Z and C to accelerate/decelerate. Direction changes move in a clockwise direction.
Please post your time in the comments. This is a dual control game. You can play as 1 person controlling both cars, or 2 people at the same computer. If you're playing on your own, you can just control 1 car if you want to. Nothing bad will happen to the other one. You can't turn around and cheat because you'd have to cross the green line which detects movement. Credit to Test_Jwl75 for the green line anti-cheat.
