Version 1.1

• Physics engine implementation.  Gravity, friction, slip, and collisions demonstrated.
• Horizontal and vertical elevators  implemented.
• Story cinematic sequence is shown every game launch but user can go back to main menu anytime.
• Added another platform where the physics engine is showcased.
• Shadows added back.
• Reduced fog effect so player can see more.
• Landing cracked earth effect improved.
• Pressing the T key will hide the UI.  More for me to make it easier to take screen shots and videos.
