This is my first Scratch project. I learned from OR2D2B's code in the "Lesson 2 (Zoom Kitty)" project that I should put the 'move () steps' block inside a 'repeat' loop. That construct shows motion better than having a sequence of 'move () steps' blocks one after the other. For details of "Moving a sprite forward in an animation" see the documentation at https://en.scratch-wiki.info/wiki/Move_()_Steps_(block)
