@plugindesc v1.1 - Just speed hacks for speeding up your test plays.
This is meant for debug only.
@help 
-------------------------------------------------------------------------
== Description ==

Testing your games is pretty slow, so I offer this speed hack solution
that will let you playtest your games at any speed that you want.

By default, the game runs at 1x speed, but you can run at 2x, 3x, 5x,
10x, 50x, 100x, whatever you want.

== Terms of Use ==

- Free for use in non-commercial projects with credits
- Contact me for commercial use

== Change Log ==

1.1 - Sep 6, 2020
  * added Game_System script call
  * added MZ plugin command
1.0 - Sep 6, 2020
  * initial release

== Usage ==

Script call

  $gameSystem.setSpeedhack( NUMBER )
  
Where NUMBER is the multiplier on how fast the game should run.

For MZ users, you can use the plugin command

  Change Speed
  
And then specify the multiplier.

-------------------------------------------------------------------------
@command Change Speed
@arg Multiplier
@type number
@desc How fast you want the game to run. 1x is normal speed.
