Spinning Metal Disks

Spinning Metal Disks are an obstacle exclusive to Checkpoint 8. The metal is on the edges, and the disks are connected by glass bars. They spin, either continuously (2- and 8-bars) or at regular intervals (3-bars).

The template Hostility20 used this.

The 3-bar disk is much more of a hazard than its slower counterpart with 2 bars, as the sudden movement may make the player crash when they least expect it, (feeling like the bar hitting on top of their head or neck). To guard against this, a steady stream of balls may be thrown, to smash a gap in all three bars.

The slower variations have rewards, either crystals or Infinite Balls Power Ups.
 * 2-bar: Two Pyramids are underneath it.
 * 8-bar:
 * Facing to the left, there are 3D Stars (Classic/Training), or Octahedrons (Mayhem). They appear twice, once for each half of the two-part room.
 * Facing to the right, an Infinite Balls Power Up is seen, again appearing twice, once for each half.
