Loved it, as someone who does sew my own clothes it felt like a lovely nod to sewists. I especially loved the old sewing machine <3.
As other people have said, the percentage dial on the sewing machine, I never figured out what it meant?
I think a tutorial stage where you make a specific dress with different patterns so you can see the changing of the fabrics, really visualise how a dress comes to fruition, would be helpful in people figuring out all the controls. Potentially a video tutorial explaining each section as well? Like a little video that plays showing the sewing controls before the sewing section for instance.
Overall I loved it, and I think the game has so much potential, and genuinely could be everything I've looked for in a fashion game. I also love the historical setting. Looking forward to seeing where this goes!
