It's been a long time and the link is dead. Here's the map that Captain Terror saved and posted it on dropbox. He's a nice guy! Linky
Here's my compo . I tested this and it should be error free. I don't know for what reason , but you may need the submerged.wad altough I included it in my compile . Oh well .....
[EDITforDOWNLOADlink] Ok here's a download link for the wad : http://dodownload.filefront.com/12221957//85bf10af32bbf89689d8afb30db3b83f8f7861408742adbd3e85c9d33a315b9442fbc868d9a61a1a
Play and have fun !
[EDIT] I'll have to spoil some things, as many of the guys I send the compo for a test said they couldn't complete it .
So , a SPOIL : when you go to the first question chamber, try not to walk on the floor. Else you fall in the pit. If you fall in it,don't push buttons. It may be obvious to do that, but that is something like second-chance chamber. Instead, grab a crowbar and apply 4-5 smacks on the computer.You'll see what happens now ;). When you're back, be careful not to fall in the pit again, and push the correct button. Then you can go back to the not-rotated stairs and press the button to rotate them .
I've spoiled a little from my compo so you can play it without being annoyed.
