In world, where almost everything is make out of blocks, you can't deny that the problem is the same as of the real world. It is a problem since there are simply too much cars everywhere that parking space is not that available all the time. You would need to wait for your turn before you can park and that is why; you need to park your car as fast as you can whenever there is an open space. If you are not going to hurry then you can't park your car. It is important that you are good at maneuvering your car since there are almost vehicles in any corner and you might get an accident if you can't maneuver your car very well.
In this game, you need to park your car several times before you can go to the exit. Try to avoid the moving vehicles as they are the ones that makes the most damage. You might get damage from anything, but the damage that you could sustain is minimal compare to that of a moving vehicle. Fortunately, there are no time limit in this game, so you can enjoy your time. You can unlock new cars as you make some progress.
