Here's how to get around in the physics tunnel. It's easy...! To make Timmy walk backwards, use the left arrow key. To make Timmy walk forwards, use the right arrow key. To make Timmy go downwards, use the up arrow key. To make Timmy go upwards, use the down arrow key. When you press the space bar, prepare to hear physics go "pop!"
As you move Timmy around, he will literally defy all laws of physics and logical possibilities! It's fun to watch, try it out for yourself.
