This is a little project that you can use to draw! There are 2 types for drawing and two for erasing! All the details can be accessed via the project’s yellow question mark button next to the size variable! I made a similar type of project when I first started scratch, but this one is a lot more advanced.
Unfortunately, it is hard to use for mobile users, so use the buttons. Recommended type settings for mobile are 1(Draw) and 4(Eraser). Recommended type settings for PC users are 2(Draw) and 3(Draw).
