I really Loveee playing this game. It's been a long time I played game like this so it feels a bit nostalgia. I just have a few recommendations.
For the sketching part it would be awesome if we could add patterns, not just colors, when sketching. Also, having more color choices and dress designs would make it even more fun.
Sewing Machine part if this part was a little easier to control. The guideline could also be more visible, especially when working with lighter color fabrics.
Fabric, Texture & Accessories
I really hope if the fabric texture would be more visibly different so that we could really feel what kind of dress we want to make.
Being able to change cut fabric without wasting it would make designing easier.
It'd be nice if we could resize accessories to make them bigger or smaller to match the outfit and more accessories.
Overall I've enjoyed playing this thanks you for making this and grateful to be a part of this. I wish to see the final version of this game quickly.
