"Park a Lot"
You are in charge of a parking lot. Don't screw it up, Parker!
When customers come, they receive an unique number and you have to park their cars. After a while they will return and ask for their car. If you are good enough in parking and delivering, and you if you do it in time, you'll earn good.
Use Arrow keys to walk and drive. Use Spacebar to handbrake and Backspace to get out of the car.
