Debug Options:
Camera Zoom/Lock (C): The play area of the game is an never ending, looping space-scape. To zoom all the way out and see how the ships move around independent of the camera, hit 'c'.

Region Grid View (V): The game renders only what is within view of the view of the player's ship. This is managed by regions. To see the region's borders, hit 'v'.

Bounding boxes (B): jME debug utilities allow for easily viewing certain things. One of these is the bounding volumes of individual Nodes. Hit 'b' to see how the scenes are made. Combine this with 'v' to see how objects change nodes by moving between regions.
