Jump like Geometry dash game

I try to make clone of Geometry dash game.Geometry dash game is jumping in parabolic way and i try to simulate jumping of square so i write this script :

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour {
    public float speed;
    public float jumpPower;
    private Rigidbody2D body2d;
    private bool grounded = false;

	// Use this for initialization
	void Start () {
        body2d = this.GetComponent<Rigidbody2D>();
	}
	
	// Update is called once per frame
	void FixedUpdate () {
        body2d.velocity = Vector2.right * speed;
        if (Input.GetMouseButton(0) && grounded)
        {
            body2d.AddForce(Vector2.up * jumpPower);
        }
    }
    private void OnCollisionStay2D(Collision2D collision)
    {
        if(collision.gameObject.tag == "ground")
        {
            grounded = true;
        }
    }
    private void OnCollisionExit2D(Collision2D collision)
    {
        if (collision.gameObject.tag == "ground")
        {
            grounded = false;
        }
    }
}

but it dosent jump like geometry dash. geometry dash jump a little also it moves a little forward. but in my script it jump fast and move down . can any body help me how to make this jump like that game.geometry dash game

I try it and was nice, but it’s far away from the systems of the original game and the news updates of the geometry dash 2.1 lauched last month.

I have also made a tutorial here on how to do this. Hope somebody finds this useful!

Geometry Dash World is the best version of the game and instead of making clone you can customize its level using the developers option.
