Play Sonic Scene Creator v2
The first backdrop you'll see is a waterfall illuminated by the bright sun. While this backdrop is great, it's not the only one you can use. Pressing the green button labeled Change Level takes you to a city skyline at night. Pressing the left green button takes you back to the first scene, while the right green button changes the backdrop to a city skyline with bright purple hues.
Choosing the backdrop is just the first step in the control you're given. You can then begin adding any elements you like. Filling out the backdrops is as simple as clicking the element you want to add and dragging it into the scene. If you decide you don't like an element, simply drag it out of the scene.
You can switch between scenes whenever you like by using the green buttons.
