This is coming along nicely! Your English is very good, although you sometimes leave out articles (the, a) or possessives (her, his) before some nouns, for example: "but he brushes her off with [a] short gesture," "After a meal he went to [the/his] workshop."
If you finish it, I'd be willing to proofread and correct it. ^_^
Also, Twine is awesome, although I can certainly understand if you don't want to transfer this much work to a new format. Still, I decided it was worth it after I tried it, so it's something to consider!
