A simple level-based parking simulator is Bus Parking 3D. You have a timer and the bus's health, and if either runs out, the level is lost. Once the current level is completed, the next levels become accessible. By collecting the in-level money along your path, you may upgrade to a luxury bus and purchase additional buses as well.
