Firefighting in Hell (Demo)

Version 3 of the "Firefighting in Hell" demo. 

Updates since Version 2:

• New Level - Limbo: A new level is ready for launch, accessible from the Start Menu.
• Reset or Replay: Victory and Game Over screens now have two buttons -- one for restarting the current level, and one for returning to the Start Menu. 

Updates since Version 1:

• Introduction Screen: The introduction screen now resizes with monitor dimensions.  
• Victory Screen. Added a victory screen upon completing the level.
• Discharge Bug. Corrected the bug in which player lost life simply by discharging hose into the ground or a fire.
• Health Drop Bug. Corrected bug where health drop rate was tied to frame rate, making health drop feel insignificant.  
• Floating Fires. Adjusted the shrink pivot of fires closer to the bottom edge of the sprite so that they wouldn't start to float when being reduced by hose. Also lowered several of them to be flusher to the ground.
• Parabolic Pressure Raise. Changed pressure increase rate from linear to negative parabolic such that pressure raises much more quickly when close to zero but much more slowly when close to maximum. This allows player to recover from empty water pressure sooner and rewards the player for holding pressure long enough to reach maximum. 
• Horizontal Thrust Multiplier.  The horizontal component of the discharge thrust now has a multiplier applied to it, allowing the player to make big leaps in the horizontal direction.
