My creation is a mystery alien world with a couple of outer space creatures on it. I hope to create a sense of novelty and adventure when the user walks in my scene. Specifically, when the user is walking, I hope he or she feel that the giant alien creature is going to fall on his or her head. (Not very successful, I confess). There's still plenty of rooms for me to improve my world, once I get more familiar with Unity.

I encountered several problems while using Unity. For example, my objects often magically vanished once I turned on the FPS Controller. I also don't know how to accurately position the objects so that they don't seem to be merged into the ground.
