C# Tilting object with acceleration on andoid

Hello, I'm making a simple topdown shooter with a spaceship for android.

I can move this ship up and down the X and Y axis by tilting my phone. The code bit for that part looks like this:

 void MovePlayer()
 {   
     Vector3 dir = Vector3.zero;
     dir.x = -Input.acceleration.y;
     dir.y = Input.acceleration.x;
     if (dir.sqrMagnitude > 1)
     dir.Normalize();    
     dir *= Time.deltaTime;
     transform.Translate(dir * speed,Space.World);
     
 }

What I want to do is to make the spaceship tilt a little to the right when it goes to the right, and a little to the left when it goes to the left. But I'm not sure how to do that, because I don't know what to check up on to see if the plane is accelerating to the left or right.

Thanks in advance :)
