without showing complete output at the end of the video, its good to have progressive output so we can have an idea about how each code interact and function to make it full
I wish you had shown the final shape as you're explaining the different paths so we can see which each 'lineTo' or others means. Honestly, without you explaining the code properly, this seems like you're just copying and pasting a code and just narrating what you're doing. Thanks for the effort anyway
