You might be expecting a car parking game here since you there is the word parking, but this game has nothing to do with parking at all. This game is about destruction as you will earn more if there is more destruction.
The game is played via mouse and the idea is to make more money by destroying anything you can get your hands on. You need to reach the star in bar for you to advance to the next level. More star means more points for you. The game requires you to think and it becomes harder and harder as you make some progress.
