The reason why this game is called "Pro Parking" is because it's a funny name. If you think about the name it has 2 P's but only 1 Player. There are no car parking games with 2 players because it would be weird.
Use the Up arrow key to accelerate, Down to brake and the Left/Right are used at steering.
In the first level you will have to choose which car is better for parking. The options are: Ferrari 458, Bugatti Veyron and Hummer H2. It's highly recommended to aviod the van because it's big and parking it is a real nightmare.
Maybe not all the car parking games are the same but this one looks a lot like many others. "Central Parking" is one example but you will find a lot more examples in the racing games of this site.
