*The first time I played, I stuck the wrench in the left tube, and was able to exit using the device that appeared. Wierd.

If you take the exit in the south room, regardless of how you do it, that's one ending.

The other ending is the exit in the device that appears after you put the wrench in the left tube; you can get there anytime. Just point the cursor high enough over the stairs, and if you do it right, the words "ESCAPE" will appear.

Of course, if there are more, I don't actually know about them.
