An example of how a parallax can be made using a single sprite (there is also a thumbnail sprite in this project). Easy to remix. Just change or add costumes in the parallax sprite, and change the backdrop and thumb sprite. The "dot" costume need to be the last costume in the parallax sprite. Study the comments inside. All code by me (@kriblo). Art is from WikiMedia Commons: https://commons.wikimedia.org/wiki/File:Town_Cityscape.svg
