I love this game! I sew in real life but haven't started a new project in a while, and this game made me want to set up my machine and get going.
I'm playing on a MacBook Pro, and I don't think the colored pencil mechanic in the sketchbook is working for me - it makes a sound, but never alters any colors, so all my sketches are the default grey. I'm also having a really tricky time with the sewing itself, but I think that's on me for trying to do this on a trackpad - the keyboard controls make some big swings, so they aren't great for the amount of intricacy the game requires, but I feel like the trackpad is too sensitive and one nudge can send me flying and force a restart.
It's also not super clear to me right now how my errors/restarts at the machine affect the quality of the garment - I'm assuming they lower my points, but I was having a hard time keeping up.
Everyone has already posted great suggestions for future updates - it's such a charming game and I really can't wait to keep playing.
