While trying to bring the cube from chamber four out the door, I managed to get the cube stuck in the middle of the door. The cube whould fling me back when I touched it, and I couldn't get it unstuck from the door by pressing 'use' on it.

The strangest thing about this glitch, however, is the fact that I could walk through the closed door! If I pressed 'use' on the cube, looked downwards, then walked forward, I would walk through the door to the other side.

It's the strangest glitch, and I couldn't take the cube back from the door, since I needed the cube to open the door.

If this glitch is already discovered, please inform me. I'd love to hear more about it.
