Get ready to take control of Sonic's environment by pressing the Play button. The next screen you see will be divided into two parts. The top of the screen will be a blank blue canvas. This is the area where you'll bring your own Sonic scene to life.
The other half of the screen contains all of the items you can use to build your own scene. What's cool about all of the items other than Sonic himself is you can add as many as you want. When you click and drag an item to your blue canvas, a copy will pop up in the lower half of the screen. This means you can choose as many items like loops or spikes as you want.
