BusMaze

Bus Maze is a 3D casual puzzle game. Players need to guide queuing passengers to vehicles of matching colors, then park the vehicles into corresponding parking spots in the parking lot. The ultimate goal is to send all passengers away.

### Game Objective

Match passengers to vehicles by color, park all vehicles, and have them drive away to clear each level.

2. Passengers Line Up: Passengers of various colors walk out from the queue lane one by one.
3. Auto Boarding: Each passenger automatically walks toward the vehicle of the matching color and gets on board.
