Here, we will create the object's Key and Door object first, and then we will create the Re-

1. Let's go to SimplePlatform | Resources | Sprites | Level in the Project view and
drag the Key object to the Hierarchy view. At the Hierarchy view, we will click
on the Key game object and then go to Component | Physics 2D | Circle Collider
