So, I have a movement script, working perfectly except one thing :
Lets say i go to the right (D button) and then i want to jump (W button), the game doesn’t register W. However if i jump and then let go of W it works?

        if (Input.GetKey(KeyCode.D))
        {
            transform.Translate(new Vector3(0, 0, -1) * playerSpeed * Time.deltaTime);
        }
        else if (Input.GetKey(KeyCode.A))
        {
            transform.Translate(new Vector3(0, 0, 1) * playerSpeed * Time.deltaTime);
        }

        else if (Input.GetKeyDown(KeyCode.W) && isGrounded)
        {
            // Instead of jumping the player teleports a certain amount upwards?
            transform.Translate(new Vector3(0, 1, 0) * jumpPower * Time.deltaTime);
        }
        else if (Input.GetKeyDown(KeyCode.S) && isGrounded)
        {
            // Teleports player down
            transform.Translate(new Vector3(0, -1, 0) * jumpPower * Time.deltaTime);
        }

So your code right now only does the first if that is true and stops there. Else if means what it is says: if the first if isn’t true try this.

So what you probably want to do is remove the else from else if (Input.GetKeyDown(KeyCode.W) && isGrounded) and you should be good to go.

Edit: I also noticed your jump will overwrite movement to the right/left. Try doing something like this (untested):

	Vector3 move;
	
	move = Vector3.zero;
	
	if (Input.GetKey(KeyCode.D))
	{
		move.x = (-1 * playerSpeed);
	}
	else if (Input.GetKey(KeyCode.A))
	{
		move.x = (1 * playerSpeed);
	}
	
	if (Input.GetKeyDown(KeyCode.W) && isGrounded)
	{
		// Instead of jumping the player teleports a certain amount upwards?
		move.y = (1 * jumpPower);
	}
	else if (Input.GetKeyDown(KeyCode.S) && isGrounded)
	{
		// Teleports player down
		move.y = (-1 * jumpPower );
	}

	transform.Translate(move * Time.deltaTime)
