This game is SO fun! As a seamstress and professional designer, I was excited to play! I have a few bits of feedback for you:
1. The sketchbook function is FANTASTIC! It's exactly like mine in real life. I'm so happy to see colors and fabric swatches
2. For improving with the sketchbook, maybe a way to reference it while you're in the fabric screen and cutting screen? I found myself going back and forth between the fabrics and the sketch because I forgot which colors and patterns I had drawn.
3. I think there could actually be less sewing. I don't need the need to sew both sleeves - maybe just the one, and it mirrors on the other side? Sewing every little piece became very tedious.
3.1 - I think the sewing mechanic should be a little more sensitive. It takes a long time to sew the fabric and turn it. Maybe even a zoom in/zoom out function that isn't automatic?
4. The tutorial was really buggy for me. I had to restart the game twice because it froze in the cutting screen. It might be nice to add an undo button too. I went through the tutorial thinking I could undo something I had cut and ended up wasting a ton of fabric
5. I think the money mechanic is fair! It gives you just the amount you need, with room to grow if you happen to mess up.
6. I adore the character design!! The art style is adorable and easy on the eyes. 10/10 design work.
