Make TORNADO visual less opaque

When using a Tornado build, we can’t see anything on the screen.

Solutions:

  1. make tornados more transparent the more there are spawned (or just make them more transparent all the time)
  2. redesign as a more suble partle effect rather than a giant polygon cone that covers everythiing
  3. nerf them into the ground so nobody uses them (haha, j/k)
