Build a 2D Game prototype in Unity 3D

This is a simple 2D Game prototype for unity. Here is a short description what the player will be able to do: The user clicks & holds the mouse button down on the ball in the center. He than drags the mouse in the direction he wants the ball to fly. After releasing the mouse button, the ball will fly in the direction the user previously decided. The mechanics are as follows: - Click & hold the ball in the center of the screen - Drag your mouse to create a direction vector - after releasing the mouse button, the ball will fly in the direction the user previously decided The graphics do not matter, a black background with white objects will suffice.
