(2D) How to make kinematic rigidbodies rotate without clipping?

Hey! I just started learning Unity, and I ran into a problem. I can't really find the answer myself, but if it was asked before, sorry. So I'm making a 2D game where you need to rotate the level to make a ball fall into a hole, but you can only see in a very small area around you. I'm just making a prototype thing now, and I have the ball and lighting done, along with a reset button (R). Now I'm trying to get the platform to rotate properly when I press A or D. The rectangle I'm trying to rotate is a child of the "Level" empty gameobject. The Level has to stay in one place and should only be able to rotate. What I have now kind of works, but because it's not a rigidbody (which prevents it from falling), it slightly clips through the ball. here's the code: #pragma strict var OriginalRot = transform.rotation; function Start () {

 }
 
 function Update () {
     if(Input.GetKeyDown(KeyCode.A)||Input.GetKey(KeyCode.A))
     {
         transform.Rotate(Vector3.forward, 2);
     }
     if(Input.GetKeyDown(KeyCode.D)||Input.GetKey(KeyCode.D))
     {
         transform.Rotate(Vector3.forward, -2);
     }
     if(Input.GetKeyDown(KeyCode.R))
     {
         transform.rotation = OriginalRot;
     }
 }

The clipping isn't very serious, but it can be a major problem later and I want it out of my way now. I tried making it a rigidbody, but gravity made it fall. I made it kinematic to stop if from falling, but then the rigidbody's addtorque doesn't work. What should I do to make it not clip, be able to rotate and stop when I want to, or at least have some inertia stopping it, while not being affected by gravity?

Any help is well appreciated! thanks in advance :D
