Question Gun recoil mechanic

I'm using the location of the mouse on screen to output an constant force in the opposite direction..I'm fairly new to c# so wasn't sure if there is a better way to do it. As of now the y direction is always negative even when the mouse is below the player and the power on the x axis is not always the same...

Code Below

/------------------------------------------------------------------------------------------------------------------------------------------\

private void recoil()
{
mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
direction = (mousePos - transform.position).normalized;
if(direction.x > direction.y)
{
if(direction.x < 0)
{
direction.x = direction.x / -direction.x;
direction.y = direction.y / -direction.x;

}
else
{
direction.x = direction.x / direction.x;
direction.y = direction.y / direction.x;
}
}

if (direction.y > direction.x)
{
if (direction.y < 0)
{
direction.y = direction.y / -direction.y;
direction.x = direction.x / -direction.y;

}
else
{
direction.y = direction.y / direction.y;
direction.x = direction.x / direction.y;
}
}

rb.velocity = new Vector2(-direction.x * recoilPower, -direction.y * recoilPower);
}

 

Is this a topdown game or a platformer?
