Need help with "Delightful Wallpaper"

[J'onn Roger]

I'm playing Delightful Wallpaper (still on part 1, with the puzzle
house), and I'm stuck. I looked at the walkthrough, but it's just a
long string of commands that take you through the game. I'd like help
on how to get past a specific part, rather than having to start from
the beginning and just follow a string of commands.

Anyways, this is what I have in the notebook so far:

Front door: flipped open/closed by peaked arches.
Leaf door (kitchen): Closed; opened by ???
Uninteresting doors: Uninteresting.
Hallway floor segment: Eastward in hall lowers; westward in hall
raises.
Ceiling opening (east end hall, northeast tower): One-way (down).
Steel gratings (around foyer): Flipped open/closed by vine arch
(kitchen).
Conservatory door (east side): Closed; opened by ???
French doors (conservatory to garden): One-way (north).
Panelled door (dining room): Closed; opened by ???
Tower bridge: Rotated by rope, foyer-dining doorway.
Tower bridge, when northeast: opened some door?
Garden door (east side): Closed; opened by ???

No matter what I try, I can't seem to advance any further. I'm
thinking perhaps my next goal is to get out of front door? Or do I
need to figure out the rest of the doors before this?

Anyways, thanks in advance for any help.
