Seeing as the English walkthrough is for 0.410 (unless I missed a newer translation), I used DeepL to translate 0.420 into English.
DeepL defaulted to British English, so panties has been translated as knickers - there may be other funny differences from the last English version
DeepL allowed me to translate 3 documents for free, but it has a character limit per document you translate, so I had to split the document into 3 parts, translate and then re-merge - No idea if that creates any other issues
EDIT: can someone update the main post to add this updated walkthrough translation?
EDIT 2: accidentally uploaded the untranslated version lol - English version coming shortly
EDIT 3: English version correctly uploaded
