FIRST SLIDE - Drag the "SIZE" slider to change the square's size. Notice how it always stays in the middle, and how its outline changes size as it gets smaller. SECOND SLIDE - You can draw! Just click and drag your mouse pointer. This version is particularly efficient thanks to @griffpatch 's code in here: https://scratch.mit.edu/projects/458048896/ THIRD SLIDE - Click to make a "tunnel" which is actually just squares that get bigger and bigger. NOTE - You are welcome to use my block for making sizable squares, just credit me! Pls lov and fav!
