If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Drive through a scary graveyard at night and try to escape the creatures that will attack you. Drive them over with your car and you will get points to your score. Use your arrow keys to control your car and the X key to activate turbo. Be careful not to crash, because the road will not be smooth. Your goal is to get at the castle in all nine levels. Have an amazing time!
