I loved the concept of snaking out your shoelaces from a central shoe, it was very original. I loved the pixel art and can appreciate how well the shoe looks (since I am very bad at drawing shoes, hehe). Everything was clear and easily readable. Another commenter already mentioned this, but I agree that having the lace share the same length would open up more ideas for layouts and future gimmicks. Otherwise this was a short and sweet little game that I enjoyed!
By the way, we played your game on our stream last night!
