Mastering Unity 2D Game Development - Second Edition

Going further

If you are the adventurous sort, try expanding your project to add the following:

• Add some buildings to the town
• Add the skyscraper skylines to the scene and give each a different Sprite renderer Color property, maybe even add a script to randomly set the color
• Research parallaxing backgrounds and parallax the skyscraper skylines
• Add objects to the foreground layer that always render in front of the player
• Add more objects to the middleground layer to create a more interesting scene
