Dungeons and mines closed door

I've been stuck in several dungeons and mines that there are always closed doors.

I understand I need clear the dungeon or get stuff done to open the door, but I clicked almost everywhere and still cannot get to the levers. Same for the mines.

Any help is appreciated!

A lot of dungeons have the special stones on which you can click. They are always in rooms, not in halways.

Mines is another thing, which part do you have problems with

In the screenshot above, there is a closed door. I went through mirror puzzle, enemy, steam puzzle, but stuck here. One thing I noticed is that there are a lot of mushrooms with light and some sort of poison fog, which doesn't exist in previous area

nvm, those are find the difference puzzle, solved

Не могу сообразить как выключить пар в шахте. По какому принципу вращать эти выключатели? Кто прошел, помогите пожалуйста.
