Rally-X DS is a remake of Rally X, a classic arcade game originally released from 1980.
In this game you control a blue Formula One racecar through a maze.
The maze is also patrolled by red cars that pursue your car. You must avoid colliding into them and avoid other obstacles.
Beaware that your blue car runs on limited gas and when it runs out, the car slows down and will be quickly overtaken by the red cars.
Currently, you can only drive around the map (same map as the arcade version).
