Friction

Description
A stat displayed at the top of the screen during gameplay, which increases when enemy bullets near the fatal point.

Each enemy bullet can add 1 point of friction; if it re-enters the vicinity of the fatal point a second time it will not add another.

Friction will not increase from certain enemy attacks (e.g. laser crescents or Phaser's dash attack), or during a period of invincibility caused by a death, but it will increase from invincibilty at the start of a game or following defeat of a named enemy, which is a key mechanic in one Matrix Orders fight.

The friction counter will reset between areas, but not sub-areas.

Friction serves a few purposes:
 * Each point of friction gained also provides 1 Mana.
 * Friction contributes to end-of-area score calculation; it is also the only Magnify component that does not reset between sub-areas.
 * Every 500th point of friction causes a Friction Break.

Friction Breaks
Once triggered, the following effects occur:


 * All enemy bullets on screen are immediately turned to small gems.
 * Phase Level is raised by 1.
 * If this is the 4th Friction Break in the game, the Tetrabiblio for Hadar will appear.
