Parking Jam
Parking Jam is a sliding puzzle about escaping a crowded parking lot. Your goal is to get the white ambulance out, but it is surrounded by other cars, so you have to shift those cars aside to open a path.
There is one extra twist. The exit is closed by a laser door, so the ambulance must first reach a key before the door will open. Your number of steps and your energy are both limited, which means you cannot move cars at random. A good solution is a short, well-planned sequence, and finding it is what makes the game satisfying.
