Mistakes

• The Tatami Room Slide Doors: I just realized in this run there are different ways of opening the slide doors. You can open them in the middle and the sides. I did open it in the middle on the first door, but I wasn't aware of this being a thing so I stumbled for a split second, but no big deal. The second door (on the way back), I did the mistake of opening it in the middle instead of to the right, which is closest to the exit. I think I did it perfectly in my All Achievements run.

The biggest optimizations available:

• Enter the Debt Box Puzzle combination faster. I'm sure you can speed it up a bit by being more risky. It's just so difficult due to having no reticle in this game to know where you are pointing.
