This is a demo of using stamp, lists, and variables to draw a row. Try remixing this to make a slide-jump puzzle game. Allow a player to move a button one spot to an empty space, or to skip over a button of the opposite color. The goal is to get the green buttons to the red button spots and vice versa.
