Ive been round and round can not find any way of beating this level :[

The note that reads "all but 1 door must be open apart from the one with the draft"... ive tried both these doors, and i cant find the hidden door it opens.

any advice?

Thanks

Edit: Solved it!

I think you've got it wrong. It says something along the lines of "if you open all but one door - the one where the draft is strongest - a secret passage opens". So you have to only close exactly one door. Now, finding out which shouldn't be much of a problem, should it?

If I recall correctly, that note is a hint for a secret room, but has no bearing on getting stuck on the level itself.

Here's the answer if you don't figure it out yourself:
