Do not click hard level or the game glitches. Click easy first, In easy, you have to race the opponent and in hard you have to chase his car. Just use arrow keys, and the blue one has a glitch that up and down arrow keys are switched, I tried to fix but it did not work so just keep that in mind and that's all, and in hard mode, you can fly but don't be slow. So to start the opponent click space and then start driving yourself.
