Portal/Chamber 01

This chamber is also designed to get you acquainted to the game, and is a simple matter of timing. As you approach the main area, you will see that there are three sections connected to the main area that have a boundary preventing you from walking directly to them. Fall into the main area, and look through the portal. It will regularly change from the section with a cube in it, to the section with a button, to the section with the exit door. When the section with the cube is visible, go through the portal, pick up the cube, and return to the main area.

You must now wait until the section with the button is visible. When it is, enter it with the cube, place the cube on the button, and return again to the main area.

Finally, you can now wait until the exit door is visible, go through the portal, and exit to the next chamber.

"Please move quickly to the chamberlock, as the effects of prolonged exposure to the button are not part of this test."
