Speed Demons is an awesome, top-down highway racing game where you control a car and drive along a highway. The highway is full of obstacles and traffic, and you need to drive to the left or right to avoid them. Every time you drive, you earn money and experience. You can also earn more money and experience by taking out other cars and hitting them.

When you take out other cars, you can either hit them hard or slow them down. You can also hit obstacles, so you need to be careful and make sure you have enough speed to avoid them.
