Trying to set gravity modifier with script

I want to set the gravity modifier of an object to 2 when the mouse is clicked down, then go back down to .3 when it is released.

I think its just a simple stupid error.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Move : MonoBehaviour
{
public Rigidbody2D rb;
public float idle = .3f;

    void Start()
    {
    rb = GetComponent<Rigidbody2D>();
    }


void Update()
{
    if (Input.GetMouseButtonDown(0))
    {
        rb.gravityScale = 2f;
    }
    else
    {
        rb.gravityScale = .3f;
    }
}
}

GetMouseButtonDown will only return true on the exact frame that the mouse button was pressed down. This means that if you hold it down, your else block will run every frame other than the one it was pressed. You can instead check for the mouse being released with GetMouseButtonUp and change it back when that happens:

if (Input.GetMouseButtonDown(0))
{
    rb.gravityScale = 2f;
}
if (Input.GetMouseButtonUp(0))
{
    rb.gravityScale = .3f;
}

or you can be more specific with your first if and then use an empty else:

if (Input.GetMouseButtonDown(0) || Input.GetMouseButton(0))
{
    rb.gravityScale = 2f;
}
else
{
    rb.gravityScale = .3f;
}

GetMouseButton will return true during any frame it's held.
