We've updated the game to include several quality of life features as well as gameplay changes:

Added the option to set the volume of the music, instead of just the mute.
Fixed the sound/animation bug when using the middle mouse button to sew.
Fixed the lingering sound bug when holding space.
Tweaked the sewing algorithm to prevent exploits of sewing over the same spot multiple times.
Changed the tutorial item to the easiest cloth - the pillow.
Made the clock infinitely slow on the tutorial cloth pillow.
Added two more items of clothes for sewing.
Grouped clothing items based on difficulty and divided them into 5 tiers to be presented in ascending difficulty.
Fixed the math when showing stats after game over.
