Hey i just started playing and I'm really liking the game so far but i had to stop and comment because of a really distracting grammar mistake. I'm not exactly a grammar nazi or anything but this was just a bit too much. (I'm autistic and a student of linguistics btw so forgive my stimming). The middle English/early modern English "thou" is a subject like I or he, it's also singular. At one point lulu says something to the effect of (this is non-spoiler btw) "is miss Liz with thou". Here she is addressing two persons whom are the subject of the sentence and should therefore use "you", as in ME, EME, and modern English this is the correct word. Your writing is really well-done and this isn't a super serious critique or anything but i just wanted to point out a little problem with it.
Lil guide for making your English sound a little bit old-fashioned:
Thou: Singular 2nd person nominative
Thee: Singular 2nd person accusative/dative
Ye: Plural 2nd person nominative
You: Plural 2nd person accusative/dative
Thy/My: used before words that don't start with a vowel sound (thy sword and my shield)
Thine/Mine: used before words that start with a vowel sound (thine arm and mine eye)
This concludes my extremely unnecessary and autistic rambling about a game I otherwise enjoy a lot and plan to support in the future.
