How to make 2D basketball game throw?

Unity Engine
1

Hi! I am starting a new project but I am a bit confused about the game I used as a reference.
I dont understand if it is 3d, 2d or 2.5d.
I think it is 2d but, in that case, how did they make that depth effect
making the ball smaller the further?¿How did they thow a 2d ball on z axis?

The game I am talking about is this:

I’d appreciate it if you could help me.
Thanks for reading it.

The depth effect seems to be from decreasing the scale of the basketball once it’s shot.

public float shrinkSpeed = 1f; // tune this to control how quickly it shrinks
public float shrinkScale = .5f;
bool hasBeenShot;
float timeShot;

void ShootBall()
{
    hasBeenShot = true;
    timeShot = Time.time;

    // launch it
}

void Update()
{
    if(hasBeenShot)
    {
       float timeSinceShot = Time.time - timeShot;

       // lerp to go from full scale (1f) to shrinkScale (.5f)
       float scaler = Mathf.Lerp(1f, shrinkScale,  timeSinceShot * shrinkSpeed);
       transform.localScale = Vector3.one * scaler;
    }
}

There are a bunch of ways to accomplish the same, but the above illustrates the basic idea.

Thanks for the answer! I will try handling the scale similar to that and see how it looks.
