    {
    	if (Physics.Raycast(transform.position, Vector3.down, GetComponent<BoxCollider>().size.y / 2 + 1f))
    	{
    		Quaternion rot = transform.rotation;
      rot.z = Mathf.Round(rot.z / 95) * 95;
      transform.rotation = rot;
    		if (Input.GetKeyDown(KeyCode.Space)) {
    			rb.velocity = Vector3.zero;
    			rb.AddForce(Vector2.up * 5000);
    		}
