WASD to move, go around the track, checker is finish, white lines are checkpoints, touch green and you reset. L/R arrows to change the track
Made in 20 min, there will be more updates that take 20 min. Added another track, and made it so tracks will loop if you keep pressing the arrow key (1 -> 2 -> 3 -> 1 -> 2 etc.). Slightly upped speed, worked on an incomplete feature for a countdown before the race starts.
