How can I enter the door at 1:30 like the guy did here?I hate this level but I don't want cheat to skip it,but I wanna finish it helping me with this glitch.Is there a noclip code to enter the door?
This game is a giant maze for me :\

I'd say it's probably some variation of this exploit.

Oh, the speedruns. Capable of destroying every game and turning it to a Mario clone.

All 3 thief games were a maze for me. So much that it made them unplayable.

Personally I wouldn't watch that guy on YT because he is a fucking idiot - that is NOT how you play Thief! It's a stealth game so try to be silent - if you speedrun you might aswell just turn on God Mode or perhaps better - play Duke Nuken 3D.

Lol wut ? He could play however he wants. Not to mention doing a speedrun requires advanced knowledge and understanding of the game. Also it could add additional challenge and be the reason for another playthrough. He should have played on expert though.

Thanks for the help.
The fact is:I love stealth games but I think Thief 1 on Normal is too hard for me.
I don't like maze-game,and this one....is terrible!

The original Thief is pretty maze-y. I'm not as big a fan of that game as many stealth gamers are for that reason along with the monster enemies.

If you think speedruns are annoying, you should watch ghosting.

I gave up.
This saga isn't for me :(
