Wanted to play this after reading all the positive reviews.

But I can't seem to get past even the first room just at the start? Wheatley says "come on lets go" but the door never seems to open? After checking the video walkthrough I can see that it is clearly not working for me as intended. I have tried restarting and even exit/start again. But just the same.

Was this broken in a later update of portal perhaps?
