The variable sliders on the top change the color and size. Press 1 to pick up the pen, press 0 to drop it. Click while holding the pen to draw.
This is the sequel to Paint, a project I made over a year ago. I have gotten significantly better at coding since then (if I do say so myself). If you would like, you can check it out: https://scratch.mit.edu/projects/412045540 However, I do not exactly recommend it over this one. And, I had promised more colors, and now we have 200! Please like and star if you enjoy, so that it can become more popular and more people can have fun. If you don't enjoy it, please comment some feedback so I can make the next version (if it happens) even better. Happy drawing.
