Good job on the walkthrough. I do have two suggestions for changes.
1. The Xbox and PC versions of this game share the achievements. So this guide will be read by console and PC players alike. Also no doubling up on achievements for the same game on Xbox and PC like Hellblade: Senua's Sacrifice for 2k in gamerscore.
Maybe adding at the beginning of the walkthrough somewhere...
"While this game is playable on Xbox and PC, and the achievements are shared between both versions, this guide is crafted around the Xbox controls. Sorry for the inconvenience PC gamers using keyboard and mouse. At the very least keep in mind that

is
right mouse click when you progress to the pacifist portion of this walkthrough. If you're on PC and using a Xbox controller, the controls are the same as console."
2. The only place I could find through the entire walkthrough that PC might need a button instruction is at the wooden berserk doll portion of the pacifist run. Consider changing the "press

to put the doll in your backpack" text to "press

(PC - right mouse click) to put the doll in your backpack" as this is the only time a left rather than a right mouse click could ruin the whole run.
