My Personal Project (WIP)

I've decided to start working on my own personal project that I'll put in my portfolio once I'm finished with it. Its gonna be a 3D jumping jumping game where the object is to keep jumping to avoid this poisonous substance that keeps on rising. It's still currently in a work of progress but I hope to get it done within these next 2 weeks. Here's the progress so far:

 private float Jump;
    public float JumpAmount = 20;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            
        }
    }
